Guitar Amplifier Repair in Newark (Nottingham)

WEBSITE ISSUES OCTOBER 2020: I’m currently in the process of doing a piecemeal website redesign. Please bear with me if there are any funny glitches!

COVID-19 UPDATE SEPTEMBER 2021: I’m currently still taking on work. Please see this page for more information.

Keld Ampworks is a guitar amplifier repair service repairing audio electronic equipment in Newark (near Nottingham). I provide a fast and friendly service that is competitively priced. Please have a look around, I’ve repaired amplifiers by all of the main manufacturers (Fender, Marshall, Vox, Peavey, Laney, Mesa Boogie) and kept my customers’ boutique and unusual designs (Cornford, Carvin, Dr Z) in top condition.

Most of the amps that I fix are valve amplifier repairs, but I do see plenty of solid state amplifiers too. I’m happy to work on modern amplifiers like Line 6 and Hughes and Kettner, but equally comfortable restoring vintage amps. Besides guitar amps, I also repair bass amps, keyboard amps and guitar/bass wiring. At this time (Autumn 2020) I’m not available for work on PA equipment, DJ, speakers, HiFi or Keyboards.

I’m pleased to say that I’ve had many happy customers – if you’d like to check out some reviews of my service, please visit the feedback page (pun intended!). If your beloved guitar amplifier or bass amplifier is in need of repair, servicing, upgrading or modifying, then please do get in touch to discuss your needs.

My History in Guitar Amp Repair

Keld Ampworks Guitar amp repair was established in 2010 and moved to Newark (Nottingham) in 2012. Before Keld I studied with the Maughan Amplifier Company, a well-respected guitar amplifier repair and manufacturer in the North of England. I gained extensive experience of amp servicing in this position and during my time doing repairs and sales for Gear4Music. Although guitar amps are relatively simple, when repairing gear it’s important to have a thorough understanding of the theoretical as well as the practical and for this reason I completed a Masters in Electronic Engineering from the University of York.

As well as the repair and design of guitar and bass amplifiers, I currently work as a development engineer designing amplifiers for a world-leading audio engineering company. As an active musician, playing in a range of different bands, I really do understand how crucial it is to have your gear in top condition!

I took my old Laney LC-30 amp to Rowan when it started to develop pops and crackles and became over noisy. Rowan... performed a full service, replaced the valves and a few other components, returning the amp to full working order. Throughout the process Rowan kept me up to date with progress. Very easy to deal with. Excellent service. Thanks again Rowan 👍read more

Been a long time, but remembered to do a review while recommending Keld to someone. Rowan added an effects loop to my... Orange Bass Butler pedal. Several months later I’m still in love with his work. Great communication, very fair Pricing, comprehensive discussions as to precisely what I wanted and updated along the way. Exactly what you want. Cannot recommend highly enough.read more

My main gigging amp was dead on the clean channels. I’d replaced the pre-amp valves myself and thought it had been... cured as I tested it at home…..but as soon as it was called on to perform live again….nothing. I run a guitar repairs workshop myself and have known of Rowan for a long while and referred anyone needing their amp fixing to Keld, but this was the first time I’d taken an amp to him. He kept me in the loop at all times, even providing me with a helpful video of his findings, which was great. Tried the amp at rehearsals the other night and it’s the monster it always used to be once again! I will continue to refer my amp enquiries his way as he’s a obviously a master of his craft. Top marks from me, thanks Rowan!read more

He also provided a full service report and PAT test. I was able to proceed to my next gig without the aid of a back-up rig. Rowan is a really nice guy and I will definitely go back to him for any future work.read more

Rowan did a great job of fixing various ailments with 25 year old Marshall Valvestate 8080 . As it isnt a valuable amp... it would have been very easy to write it off as an uneconomic repair . Rowan listened to my list of symptoms , proposed a rough guide to the costs of repair before working on it and said he would check before doing any additional work if required so as not to go into too much cost . Amp is now back to 100 % health PAT Tested and ready for another 25 years of service . Excellent friendly service from someone who you can have total confidence in . I have another dodgy amp working its way to him soon and look forward to seeing his specialist knowledge at work again .10 out of 10 with all the bells and whistles !read more

I approached Keld about a fault with my much-loved Ibanez TS-9 Tube Screamer. The fault was found promptly and remedied with good advice given about how to avoid such issues in future.
