This wireless mic repair came in from the singer of Newark soul band the Acetones. Both units powered up but no sound came from the receiver when the mic was used. Upon investigation I discovered that the transmitter and receiver were able to communicate. They use 2.4GHz. The unit has 6 wireless channels, all of […]
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.

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!
In October last year I fixed this wah pedal repair for a lincoln customer. The pedal would not turn on, possibly as a result of the user plugging the wrong power supply in. Often pedals aren’t economical to repair, but a unit like this is normally worth it. In this case it was a fairly […]
My customer brought this Laney VC30 from Worksop to my Newark workshop complaining that the clean channel distorted. It’s a pity, because he’d kept it in pristine condition! Two other attempts had been made at repairing this fault. One by Laney themselves, and one by a local electronic engineer. Both had fixed the problem temporarily […]
A smoke machine repair, brought to my Newark workshop by a Grantham based DJ. This is a fairly simple unit: A power supply, a thermostat and a relay to control the power to the smoke heater. There is also an external remote on a 6.5mm 3 pole jack cable. The customer was finding that the […]
This LED lighting repair was a bit of a horror story! Aside from fixing the problems with the two lights brought in, they needed several modifications to improve the unit safety. They were brought to me by a Grantham based DJ. One of the lights wouldn’t power up, whilst the other had a flicker on […]
This DJ Mixer repair was a bit of a departure for me, but I did it for an old customer. The mixer is getting a bit long in the tooth: the send and PFL (pre fade listen) buttons were intermittent, the faders were scratchy and an intermittent fault with the echo unit. The faders were […]
This Marshall Valvestate repair was performed in an advisory capacity for a friend who’s got some electronic and soldering skills, but needed a hand with the fault diagnosis. It was an interesting job so I’m writing it up alongside my normal repairs. The amp is a Marshall Valvestate 8008 power amp. Despite the name it’s […]
The symptoms exhibited by this Trace Elliot GP12 repair were a loud hum and distortion evident during note decay. Unfortunately I wasn’t able to replicate the customer’s problem which makes repair difficult, so I took a number of steps. I left the amp on soak test for 2 hours, which involves heavily driving the output […]
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 […]
The majority of my work is amp repair, but occasionally I’m asked to do a pickup replacement by a customer who knows my work and trusts that I’ll do a good job. I’ve been changing pickups since long before I started amp repair so I’m always happy to take a pickup replacement job on. The guitar […]
