Guitar Amp Repair
Repair & Service for Guitar Amplifiers.
We see many more guitar amplifiers than any other form of electronics stage equipment to repair, it’s not because they are more problematic to failure it is just they are more popular and are often used for other things such as bass amps, piano amps and so on.
The most common form of repairs are
- broken Pots
- crackling pots
- Damaged jacks
- Hums & Crackles caused by dry joints, leaking capacitors
- Blown Elements
- Played too loud and let out some smoke
- Rarely it’s human error – We try to understand how you use the kit and offer suggestions for best results
There are two main technologies we repair in guitar amps, this is solid state, and valve. The term solid state simply refers to no moving parts and all ‘solid’ referring to the silicone transistors and FETS used to amplify and deliver the current needed to the speaker. Valve amps however use electrons travelling through a vacuum to amplify the current. The blue glow tinge you see on power tubes is plasma and is as close as you can come to seeing electrons moving.
Amps are dangerous inside
Both amplifiers technologies contain dangerous voltages and users are not recommended to start prodding around inside. We have had many amps in over the years where a video clip on ‘repairing amps’ is used and often creates many more faults. For many people their guitar amp is their tool to earning money, and needs to be carefully repaired and looked after.
