6 sizes guitar techs use all the time
These three double-ended wrenches fit jacks, pots, switches, bridge studs, stompboxes… Just about every wrench you need for guitars and amps.
Quality hard-plated steel
Slim enough to slide under control knobs, and into tight spaces, but tough enough for professional repair shops.
"Now I have the most common size wrenches fit right in my guitar case. Very cool."
—Erick Coleman, Repairman and StewMac Tech Adviser
