I really want to install a Kill Switch onto my guitar ala Johnny Greenwood as it seems to be a really cool gadget. Ive been researching various methods and im definately going for one which doesnt involve drilling my guitar to shreds. Anyway Kill Switches are awesome and although the natural killswitch using the pickup selector is cool I want a proper one.
I've got a Fender Jag and a Epiphone SG so I can pretty much Killswitch anyway but yeah I have to agree with you, its an awesome technique that's really under appreciated.
I am however thinking of getting a Tom Morello-ish strat done because as you say, proper ones are awesome.
