Is there a place on a regular Strat to put a killswitch without drilling into the wood? Like, is there a spot in the control cavities that has enough room for the switch, so I'd only have to make a hole in the pickguard?
Take the scratch plate off and find out?
beside volume knob, above the 5way-switch. maybe??
Use a push/pull pot...
yeah maybe between the pickup switch and volume. or take out one of your tone knobs and replace it with a killswitch? you would have to rewire your guitar though obviously
