i had this happen to me last night...
we were the first of two bands... we finish our set (50 mins) and immediately began to break down to get out of the way of the following band (i was curious why they hadn't set up their gear behind us for ease of transition reasons).
bassist in the 'headlining' band comes up, doesn't even introduce himself, and says, "hey, you sounded really good.. is that your amp?"
-yes
"listen, i thought the venue was supplying an amp. is it ok if i use yours?"
-no
must not have listened to me because after i cased up the head, he asks again one min later, "i can use your amp, right?"
-no
"oh, why, you leaving?"
-no, i just don't loan out my stuff.
talk to the Fred [soundman], have him patch you direct...
sound guy is telling him his speakers can't handle it, despite the fact that they are big boy JBL's... not my problem.
i felt like kind of a dick but who the hell shows up at a gig assuming there's a house rig for them to use? our drummer let their drummer use his kit since it was already set up but that doesn't bind/obligate me to do jack-all.
this was not an open mic/invitational, it was a booked gig.
meanwhile, dude had walked in earlier with his bass -- no case -- from the pouring rain and i'm thinking if he takes this type of care of his bass then who knows what he'll do to my rig..
