About OX4 Guitar Pickups

Each pickup is made to order, hand wound and assembled using the best materials and components available.  I make the baseplates, covers, slugs and keepers with vintage correct materials.  My pickups read anywhere between 7.1k to 8.9k.  I dont pot them either. I’m very proud to have worked with some truly amazing Musicians from all over the world..Paul Stacey, Larry Carlton, Les Davidson, Trevor Keith, Dan Gig Rig, JD Simo, Matt Schofield, Ed King, Greg Martin, Darren Randall Glover, Flash Lightnin, Roman Rist, Carter Vintage, Jam City Guitars, Ben Lloyd Sleeping Souls, Jason Isbell and many others. Thanks for using Ox4!

“Hi Mark, Pickups installed in my R8. I’m really pleased with them. Had a chance to try them out at proper volume over the weekend and they sound great. Lovely vintage style to them”. - Stuart Marks – UK

“Hi Mark. Got the pups installed yesterday and took them for a short test run. I really, really appreciate the sound and the dynamics I get! Pups are installed in an early 70′s Les Paul routed for ordinary hum buckers. Big thanks! I will definitively recommend your pups for anyone interested. Cheers!” – Jonas Freden -Sweden

“I’ve been playing your Low Wind set in my 1992 LP Std. for couple of weeks now, and let me tell you, you’ve really got something going on there! Long story short..Mike Bloomfield.. you know what I mean, this is the wonderful clean sound with just the right amount of bite.. so vocal and responsive to touch.. But there is so much more going on, that just can not be heard on recorded music…As always, one has to play himself, to appreciate – like the impression of space, feels like hearing both coils separated and at the same time together!” - Tomas Vanecek – Prague, Czech Rep.

“I really love the sound of your Pickups, even the Luthier himself was blown away by the tone and quality.It turned into the best sounding Les Paul of my collection.” - Michael Marti Switzerland

“Hi Mark, well got them where i want them now…they are extraordinary mate..thank you very much.  I am inspired and your pickups are the sound i have longed for…so articulate and open, they are brilliant how the fuck do you do it! I am going to be buying another Pickguard from Grosh guitars soon and this will be for strat PUPs, so i can interchange them with the HB so will defo be coming back to you for some 50′s pups from yourself. Once again Mark than kyou very much bloody amazing work…just SOOOOOOO much better than the others..cheers” – Mark Wishart – UK

“Hi Mark,

Sending you some pics of my R8 Iced Tea with your pickups installed. They sound really great! Couple things stand out to me compared to a #$%&-load of other boutique pickups I have tried:
The neck pickup is really warm AND clear sounding while still maintaining a punchy low. Second thing is how clear and bright the bridge pickup sounds without getting harsh and spiky. I really love how balanced the tone of the bridge is. To sum it up in one word: balance! Cheers and keep up the awesome work!” – Ole Petter – Norway

“Pickups received and installed! They sound amazing mate really really impressed! So clear, articulate and a big step up from the standard custom buckers. As I work in a shop I had a chance to A/B against a regular R8 and a £7K True Historic and I’m pleased to say my guitar with your pickups smoked both of them!” – Ben Scarr – UK

“Hi Mark, Got the pickups today and promptly installed. Had to play around a bit
with the heights compared to what they were (lower neck, higher
bridge) and holy shit these sound every bit as good as I had hoped and
more! Neck pickup would easily be the best sound I’ve ever heard from any
guitar with a HB in the neck both clean and with medium and piles of
gain, really does retain clarity and note separation. Really cool bass
response too. Bridge pickup is incredibly useable now and really shines clean and
again I don’t think I’ve heard a bridge HB sound this sweet clean into
my DRRI. Really nicely balanced and again doesn’t lose clarity when
winding gain right up. Really impressed, thank you again!! - Steve Girolamo / AUSTRALIA


“Mark, I got the pickups installed (finally) and I’ve been playing almost non-stop the last couple days…Unbelievable job man, these pickups are absolutely stellar. Somehow you were able to capture the tone I had been chasing in my head for so long and my Les Paul finally sounds how I dreamed it should. Great fucking job”. - Ethan Navarrete / USA

“My 2007 Gibson Les Paul R7 has sounded dull and harsh since the day I bought it.  I could manipulate the volume and tone controls to make it usable, but it was by no means versatile.  I recently replaced the stock Burstbuckers with Mark’s OX4′s and FINALLY love this guitar.  I can hear then character of my Deluxe Reverb amp in a way that wasn’t possible before.  They clean up great and really bite when turned up.  Much more tonal depth and character than before.  I’m very happy with the transition.  I highly recommend these pickups if you’re in a similar situation” - Brent Winzeler / USA

“Just got the pickups in the Paul, and they sound unbelievable. Exactly what I was looking for. That middle position is Pagey as it could be. Nice bright neck pickup, makes a world of difference. Thank you!”  - Jason Isbell – Nashville/Muscle Shoals

“Hi Mark, So, I finished installing the pickups on Friday evening and played the guitar a lot since then. It was not just an upgrade, it was simply what it needed for years ! It now sounds like it should have and I just love it. It’s way more articulate, full and has this vintage vibe I love. I won’t be able to try it in a band condition for a few weeks, but I’m almost sure it will become one of my main guitar from now on. I might name my guitar ‘the kraken’ since you released it. I attached a quick picture of my guitar for you to see the result. The pickups fit perfectly on it with their aging, it’s awesome. Now I feel that my SG should also get some new pickups at some point, I think I’ll just contact you for some more in a few months

Anyway, thank you a lot for your work !

Cheers” - Matthieu Daladouire – France

“After a very easy transaction, I had the pickups within a week. A very competitive time for custom made boutique pickups. Got them installed in my Gibson Les Paul Standard Faded and they scream. The cleans are amazing. They have this amazing nasally chirp or honk you associate with late 50′s PAFs. With a bit of overdrive, they scream. Quality company, quality service, quality product and legendary tone. Thanks Mark, I’m sure you’ll be hearing from me again!” - Lee Bates – UK

“Vintage Tokai LS80 and Ox4 Humbucker. Both high-quality craftmanship, both handmade with love. Can´t imagine a better Les Paul sound. Affordable Tone Monster!” - Alex Schaser – Germany

“Hey mark. They’re in. My fingers are sore from playing the last 5 hours. Can’t put the guitar down. Great fucking pick ups. Thanks so much”- Bob Hyatt – USA

“Having never had the pleasure of playing a real 59 PAF pickup, I cannot compare that to these OX4s, however I simply couldn’t imagine any way these pickups could be improved upon. The single note clarity under higher levels of gain is unheard of and the sound is so thick. These definitely have the upper midrange chirp. Joe Bonamassa, Robben Ford…eat yer heart out!” - Phil Robinson – UK

“Hey Mark, Pickup all installed in my Mick Jones ’57 Les Paul Custom, NOW it sounds like Foreigner!
LOVE LOVE LOVE IT!!!” – Bob Marsh – Mad the Martian 

“Hi,Installed them in my 02 R8, and played it tonight. Very pleased indeed! Great fat sound from the neck without any mud and sweet full bridge pickup. A real rocker! They sound equally good clean or distorted.  Cheers!” –  Björn Greder – Stockholm

“Received my Ox4 Paf Neck/Bridge Clones today .. installed them in my CC #16 Ed King (Redeye) and wow !!! They sound excellent thank you !” - Zeke Downey – USA

“Got my baby back today. OX4 Pickups installed and I’ve got to say, this is one beast of a guitar. “Holy cow” – Matt Anthony – USA

“Mark, I fitted the Blues breaker pickups yesterday and they are bloody marvellous, I love them, thank you. I’ll be ordering a set of aged PAF’s as soon as I can afford them. All the best.” - Chris Moores – UK

“The OX4 pickups sound magical in my Les Paul. For the first time in a long while I am torn between the bass and treble pickup during a solo. Such is the quality of the tone each easily produce. I could simply not be happier. Great job Mark. Cheers.” – Phil Astles – UK

“Hey Mark, Got the pups installed them this morning. Son of a bitch dude. You got a hell of a talent . I’ve had a lota  boutique pups but these are the stuff. I’ll sent you a pic of the guitar with the Ox4s in it. Don’t know what to say as I’m still a little blowed away, but thank you very much.” – Steve Reynolds – USA

“Steve from s/a ampworks,and guitarist with herts band,strawberry letter 22,i asked mark to make some strat pickups a while back and he has responded big league,i have the priveledge,of testing the 2nd or 3rd prototype set in a r/w board strat,i have played strats,from all era’s 50′s 60′s 70′s and forward to now,these/that guitar and 65 fender deluxe reverb,is for me best strat sound i can ever recall having,these are not officially available as yet,i thought mothers milk,were going to be the ultimate,in fact they were ok,but not fit to play in the same ballpark as these,congratulations marky boy you have nailed it bro” –  Steve Dove – SA Ampworks

“Hey Mark, you’re a magician mate! Got your standard pafs installed in my Les Paul and 336… They have taken both guitars to the next level. A more open and controlled tone than before, just more like a traditional Gibson sound really. I strongly advise anyone looking to transform their guitar, give Mark a call! Great service, great product and superb value for money. Sweet!” – Jules Fothergill – UK

“Hello Mark,
I don’t speak English very well so it’s very difficult for me to describe with English words the sound of your pickups. But I can tell you that your pups are just fantastic. They are really incredible. The notes are very well defined and the riffs are heavy, powerful and extraordinary dynamic. Everything I have read on the sound and quality of your pickups is true. I don’t know what is your secret of making but don’t change anything and you still continue to make happy a lot of guitarists. In conclusion, I’ve finally found the clone PAF that I was looking for and these OX4 pickups will remain long installed in my guitar. I’m very satisfied, thanks a lot Mark”. - Michael  - France

“Hey Mark, I got my guitar back from my tech after work today with the new pickups in. I set the pickup heights to the rings as you suggested and have to say they are AMAZING! Thanks so much. I’ve only just stopped playing since I got back from work. Keep up the great work!” Simon Chell – UK

I’ve recently had Mark make up a pair of Jimmy Page No’ one Gibson pick ups and now fitted into my JP Les Paul I’m blown away with the sound, seriously I’ve tried other makes and they are not even in the same ball park. Spend ya money wisely and invest in some Ox4′s you won’t regret it. - Tony latter – UK
“Tone nerds: Just got a set of @Ox4pickups PAFs in the LP goldtop. Changes everything. Incredible pickups, guys”.  - Jason Isbell – Nashville/Muscle Shoals

” Mark,I got the V back from my luthier today and your pickups have brought it to life!  There is just such clarity and presence in the sound, it has the most vocal tone of any guitar I own. It genuinely competes with some of my favourite vintage Fender single coils for sparkle and overtones in a way I’ve never heard from a humbucker before and the out-of-phase middle position adds a whole new dimension.
Really exceptional job on these! Thanks so much, Cheers” – Dan Kats – UK

“Hello Mark ! I’ve received the PUs today. They are now installed in my 2001 Navigator N-LP380. A little set-up to find the right sound on my guitar and…I’m very happy, they are really great sounding PUs with that tone you get on old guitars. The Alnico IV PUs are well-balanced, clear and dynamic.

I have many vintage guitars (Gibson and Epiphone from early 60′s with P90 and mini-HB) so it’s quite easy for me to compare the tone with older PUs from the golden era of Gibson. Great job!” – Mr X – France

“Received my set of OX4′s today. Within 20 minutes of opening the box, they were installed in my Les Paul and were screaming through my little brown princeton. I am so stoked with these! Everything I hoped they would be and more. Thank you for your awesome work!” -Dave LeRoy Biller – USA

“My beautiful Rist Showhorse from Roman Rist just got a set of low wind OX4 pickups (6.9k neck and 7.5K bridge). Wow they are amazing! I am such a happy guy right now. Thanks for making such a killer product. I have been through a couple of sets of pickups in this guitar (from very big name pickup makers). Roman told me about he OX4 and I heard some clips of his other Showhorses with them in it. I will have to admit I was a bit skeptical due to unfulfilled expectations after many other humbuckers. Well I am not any more. These things are just perfect. The tone and feel are outstanding. I don’t know how OX4 has done it where so many others have failed, but there is something special going on here. Get yourself a set of these. Thanks again” – Stevie Blue -USA

“Hi Mark, Pickups arrived, installed and got their first gig under their belt.Certainly one of the best set of pickups I’ve played (and I gone through a fair through in my time). I first installed them on my number 2 Les Paul, but they lasted 5 mins on there and went straight on the number 1. Sound unbelievable through a Marshall 1958x. Thanks!!!!” - Dave Diston – Switzerland

“Hello Mark! I received my new pups and I am blown away!  Love them! Thanks man! – Justin Jarvis – USA

“Hey Mark! I just finally did a gig with my R8 where I could really hear these pickups. Good God do I love them!!
It was just my Darkburst R8 plugged straight into my Vox Cambridge. The middle position is just wow” – Steve Selvidge – The Hold Steady

“This Greg Martin’s clone set is just amazing !! It fits all my expectations, it is the perfect mix between clarity, articulation and growl.” - Arnaud Kauffmann – France

“just wanted to drop you a line and let you know how happy I am with the pickups. I have them loaded in a 60′ Historic Les Paul and they are a huge improvement over the stock Burstbuckers. These pickups have everything…detail, warmth, just the right amount of bite and they sound fantastic clean or overdriven. This is about the closest thing I’ve heard to a real PAF. I’m going to order another set for my 335 soon. Thanks again for the great service.” – Tim Collins – USA

“Hi Mark, I’ve put the pups on my Orville and the sound is authentically killer, now I can say there’s a mojo workin’ for me! I am in love with your PAFs, great work Mark, I will use extensively this set of OX4 pickups in my next album” – Federico – Italy-  http://www.urizenkramer.com

The clarity is remarkable- just like a PAF. They sound better with just a little hair as opposed to alot of overdrive. It didn’t take much tweaking at all- and the balance is great. And they look great. - James Cichy – USA

“Finally had time to install the pickups!!!! Got to say I’m over the moon with them. They replaced a set of custombuckers in my R8, the difference is like night and day! I’m seriously going to order another set to replace the Seth Lovers in my Knaggs Kenai. Outstanding work Mark.” - Mark Leeson -UK

“I received my pair of OX4 a few days ago and installed them in my R8. I am a huge fan of the Mule. But I’ve to say that the OX4 sound just fantastic. The definition and clarity are incredible. They have a lot of personality. More than my lovely Mule who are a bit un personal. (which can also be a quality)They’ll stay for a long time in my guitar. Great thanks to Mark, who’s a really nice and serious person. Great job, quick shipping. And he answers quickly to all the questions I had.” – Michael Rouge – Switzerland

“Today morning I got the guitar back and I’m blown away by the tone and looks. The pickups are stellar! Truthfully, I didn’t expect them to be so outstanding, …especially the bridge pickup, … I can’t find words, it sounds like a bell, so clean and pure, simply awesome!

Thank you for turning a ok guitar into a tone monster! I’ll recommend you to all Les Paul players who think of a pickup swap.” – Rainer Mischon – Germany

“Mark, a note to let you know how much I love the OX4′s in my Les Paul conversion. My friends Ed King, JD Simo, Gary Bohannon, and Jim Weyandt were on the money about your work. I own a beautiful 1958 Les Paul, plus a couple other Gibson’s with early patent pickups. There is a special compression with the early Pup’s, you absolutely replicate that with the OX4′s. Keep on trucking brother, you have nailed the tone, now I just got to play the right stuff!!” - Greg Martin The Kentucky HeadHunters

“Mark, Love them, Awesome, Toneful, Articulate, Musical, and balanced with excellent string to string separation. I fully endorse your pickups as a paying customer. I am VERY pleased.” –  Roman Rist / Rist Guitars – USA

“Killer sound, clear and dynamic. I’m so impressed by the vintage tone I heard. My CC#16 deserved  to have great pickups, it´s done thanks to Mark!” - Thomas Letailleur – France

“The Mark Stow pickups are incredible…more compression than others I’ve heard.  VERY similar to my 59.  I have a friend who put his pickups in a new Allman LP and the sound sold me.” – Ed King – Nashville

“The PUs sound phenomenal in my Lester … waaaahhhhoooooooooooooo!
Paired with my 68spec’ed Metro Plexi – this thing is just smoking!

Thank you so much!
Keep going the good work :-I

Wolfgang” - Wolfgang Schuneritsch

Just wanted to let you know I got the pickups today, I’m blown away by what I’m hearing through my amp and I’m sure I’ll be back for more – Steve Henning / Henning Amplification

“Man that’s Great!! I finally got to play them last night for a bit!! They sound fucking wonderful mate!!! I’ve heard lots but you really have it right!!” - JD SIMO /Nashville

“These are the best aftermarket pickups I’ve ever heard. It’s all about clarity and OX4′s have that clarity that I’ve only ever heard in old Gibson pickups. The only pickups that compare to the original Gibson PAF’s and Pat #’s supplied from the late ’50′s thru the mid ’60′s… are OX4′s. I love OX4 pickups!” – Gary Bohannon / Nashville

“Hey Mark. I finally had a chance to try out your pick ups  not sure what you did here, but I think you sent me a GREAT set of original PAF’s by accident!
Man, you have hit the nail on the head with these. I am going to AB them with a whole slew of other pick ups  I have maybe 8 or 10 sets here to try out, including some originals (two sets) and some Pat No.’s but I will be surprised if any come close to these” – Tom Bartlett / Bartlett Guitars

“I’ve tried a few replicas and these are the only ones that match the sound in my head to what a vintage PAF should sound like to me” – Lewis Grey

“I have to say…you have blown me away with these pickups. They aren’t just small jump up, the difference is night and day. Such a bell like tone…the middle position is not just usable…it is now my favourite position. In the words of DanGigrig…you’ve knocked it out the park. I will recommend these highly to anyone and everyone…and shall I get a new guitar in the near future…I will be ordering another set in a heartbeat. Words failed me when I plugged in…such classic tones.
I am converted. 10/10 from me.”- Dave John

“Mark made me a set of gold PAFs for my early 80′s Flying V, and completely knocked it out of the park. If you’re looking for the ultimate set of PAF pickups, you’ve found them” – Daniel Steinhardt – TheGigRig.com

“After installing the OX4 humbucker in my Les Paul studio, I completely forgot about the previous custom pickup I was so fond of. The OX4 is without a doubt my new favorite. Smooth, creamy overdrive and focused midrange. Just the way I want my guitar to sound. Mark makes a quality product that I highly recommend.” - Trever Keith – Face to Face

“Mark is totally dedicated to what he does and the pickups he did for my Precision Bass we’re exactly what I was looking for”

Adam Hinton - Bassist / Aptik Limited edition apparel

“I have tried ALL the PAF clones, Mark’s are the best”

Paul Stacey – Producer / Guitarist

“The pups on my SG sound fantastic! The closest thing to PAFs I’ve herd. Thanks man!

Les Davidson –  Guitarist

These are the closest thing I’ve heard to a PAF – I’ve also tried, but “Ebay’d” the following – Gibson Classic 57′s, Gibson Burstbuckers, WCR Fillmore, WCR Darkburst and Lindy Fralin PAFs.

“I’m on my 4th set of OX4′s! My favourites are 8k4 in the bridge 7k3 in the neck! Compared them to a set of Pat # PAFs in the same guitar – VERY CLOSE!!!”

Simon Keats – Origin Effects

“After my experience with Mark and OX4 Pickups I know that I’ll always choose his pickups in my guitars. The quality of his work and the friendly customer service is on par with the best guitar pickup manufacturers in the world.”

Mircea Burtan – Guitarist
