Fender Hod Rod Deluxe Repair
Fender Hod Rod Deluxe Repair

This is the world’s most popular valve amp [citation needed], meaning I get a Hot Rod Deluxe Repair quite regularly. The amp has two common faults, which are well documented. The first, and most common is the grey ‘IC’ (Illinois capacitor) electrolytic caps which are prone to failure. Fender use these presumably because they’re the ...

Blackstar Series One repair S1-104EL34

This Blackstar Series One repair from February was a bit of a mess! The amp had unfortunately received the unhelpful care of another repairer who had left the amp in a terrible state. If you don’t like to see damaged PCBs, look away now. It was brought to me because it was blowing fuses at ... Read more Blackstar Series One repair S1-104EL34

Marshall Silver Jubilee repair – Marshall model 2558

I was quite intruiged when a Nottingham guitarist brought this Marshall Silver Jubilee repair to my Newark workshop. These amps have taken on a bit of a legendary status, due in no small part to their association with Slash and Joe Bonamassa. I love how this amp looks, and it’s got an interesting tone control ...

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!
