I will only lend kit to trusted friends, as to anyone else, absolutely NO.
I had a vintage Trace Elliiott Head destroyed at a big charity gig, It was DI'd and I told the other bass player not to touch any of the controls, when I went on stage I found he had cranked everything up full, it was distorted and wrecked,
We all work hard and strive to get our ideal rigs, and I hate phrases like....' I didn't mean to do it mate' or ' must've been faulty pal'
DO NOT LEND KIT, unless you know and trust them.
