Kirk Hammett

The concept of clearing one's mind before performing a task so that it is consumed by nothing but that task, yet is open at the same time to anything that might happen - that concept can be applied to playing guitar, and it's enormously helpful for improvising.

I think I could walk into any music shop anywhere and with a guitar off the rack, a couple of basic pedals and an amp I could sound just like me. There's no devices, customized or otherwise, that give me my sound.
