About Amp Valves

Amp Valves are tubes for guitar amps allow you to change the sound of your amp. How often you have to change amplifier valves depends on how loud and how frequently you play. If you are a touring musician, it would be very sensible to travel with spare amp valves. Playing loud every night, as well as being lugged in and out of vans, is a hard life for an amp valve so have replacements at the ready.

If you're more of a home player, valves should last several years before burning out. Different amps need different valve types so it’s important to get like-for-like replacements. Power Amp or preamp valves can fail but a replacement can be readily acquired and your guitar amplifier can be restored to full power. We offer a range of valves/tubes from EL34s to KT66s and more.
