You've had it re-wired as well?
Yeah, but the only change I've made is to the tone control. The bottom one —the one that's normally used for the tone of the middle pick-up — that's now a master tone control. I didn't want to change anything on it for years but, two years ago, I got fed up with clicking on the treble pick-up and not being able to adjust the tone. The idea of the Strat, I suppose, is that you're able to adjust the tone on the bass and middle pick-ups and play rhythm on those and then swop over to the treble pick-up and do a solo —like Buddy Holly. The other tone control doesn't do anything, so I've just got master tone and master volume — it suits me fine.
