Frequently Asked Questions
How much does amp repair cost?
A lot of amp techs look at the amp first and give you a quote after, so posted prices are hard to find. Among the shops we checked in September 2026 that did post an hourly rate, the typical price was $100 an hour (10 shops, from $60 to $140). Seven shops posted a diagnostic fee, the charge to open the amp up and find the problem, and the typical fee was $75 (from $35 to $100). Some take that off the final bill and some don’t, so ask. Parts like tubes usually cost extra. There’s more in the amp section of what a guitar setup and other repairs cost in 2026.
Many amp techs work on effects pedals too. For what pedal repair costs and which shops take pedals, see our guitar pedal repair guide.
Is it worth repairing a guitar amp?
Usually yes. A quality amp (tube or solid-state) is almost always worth repairing if the fault is electrical rather than structural. Tube amps in particular are built to last decades and hold their value well, so a cap job on a vintage Fender or Marshall can protect an amp worth far more than the repair. The exception is a low-end practice amp where repair costs approach or exceed replacement cost.
What are the most common guitar amp problems?
The most common amp faults include: tubes wearing out or failing (especially in high-wattage tube amps), dried-out filter capacitors causing hum or poor response, crackling or cutting-out caused by dirty or failing potentiometers, blown speakers, faulty input or effects loop jacks, and power supply issues. Most faults are repairable by a qualified amp tech – if your amp is making unusual noises, cutting out, or not powering on, a diagnostic is the right first step.
What's the difference between tube amp repair and solid-state amp repair?
Tube amp repair requires specialist knowledge. High-voltage circuits – often 400–500V DC – remain dangerous for hours after the amp is unplugged, and tube circuit diagnosis requires familiarity with transformers, bias points, and point-to-point wiring.
Solid-state amp repair is generally lower risk and often less expensive, but modern digital modeling amps can be complex to diagnose without manufacturer service documentation. Not all amp techs work on both – check that your chosen shop has specific experience with your amp type.
How often should a tube amp be serviced?
Most tube amp technicians recommend a full service every 1–2 years for regularly gigged amps, or every 3–5 years for home practice amps. At minimum, power tubes should be checked annually and replaced when worn. Filter capacitors in vintage amps should be replaced every 20–30 years regardless of whether a fault is present – old caps can fail suddenly and cause serious damage to other components. A tube amp service typically includes tube testing, bias adjustment, and a full electrical inspection.
