Guitar Amplifier Repair in Newark (Nottingham)

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, PA equipment, DJ, speakers, HiFi.

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!

This is a Fender Deluxe 90 DSP Repair. It came to me with a an intermittent (but very loud when it happened) crackling noise. The problem was with the Digital FX unit and the main amp and was easy to fix once it presented itself. It was repaired under my minimum fee for 1 hour’s […]

HH amp Repair

It’s a full solid state oversized 1×12 combo with two independent channels. The tube emulation circuit seems to involve distorting a […]

Broken footswitch repair – MXR Carbon Copy

This broken footswitch repair was sent to me because the owner suspected that his pedal had the ESD problems that I’ve documented elsewhere.  Actually, the footswitch was broken by mechanical use. This is comparatively rare – MXR use quality ‘Alpha’ parts for their footswitch. The unit was soon fixed, and shipped back to its owner, […]

Dyna Comp Repair

MXR Dyna Comp repair

The Dyna Comp is possibly the most famous of the compressors used on guitar. This Dyna Comp repair was similar in nature to the ESD fix that I’ve documented elsewhere in relation to the Carbon Copy pedals.  The issue is with the switching circuit – the FX does not switch in when the pedal is […]

Peavey Valve King Repair

Peavey Valve King Repair – VK100

My customer brought this Peavey Valve King repair in to me before Christmas  to get an opinion on its state of repair. The amp was blowing fuses. The Valve King VK100 is a monster of an amp. Not fire breathing levels of gain like some Peaveys but a big and heavy brute with a classic sound. […]

Carvin repair

Carvin repair – Nomad 

This Carvin repair was completed for Simmonds music in Grantham. They received the amp in part exchange. The amp would occasionally drop to very low volume, with no apparent reason. From the beginning it was obvious that the Carvin repair had been attempted by another tech in the amplifier’s past. The first valve stage had […]
