(hey guys, it's been a while!)
I definitely think the wood, pickups, and strings matter a lot, but also the amp. Not even just the pre/power amp, but the cab. The cab you use, and how it's mic'd up (if you're recording) makes up probably more than half of your tone. Even two cabs with the same type of speaker can sound completely different. Putting a 5150 through a Mesa oversized with v30's, will sound infinitely different from a Marshall cab with v30's.
Just my two cents, but I believe it to be true! :rock-on:
