Here's my scenario and maybe others will have similar scenarios as myself. Keep in mind this is a semi tounge-in-cheek post. My guitar player's main "axe" is a B.C. Rich warlock. Words cannot describe my hatred for this guitar. Every time I'm at a show and see a band using these I think "here comes a crappy metal band" nine times out of ten I'm usually correct in that assumption. I'd at least like to get the benefit of the doubt before we suck it up on stage. Now my drummer and I both equally hate this guitar with a passion we've hoped and prayed this thing would get lifted at a show so we would never have to see it ever again. He's a bit more vocal on the subject than myself. I just offer for him to use one of my guitars(or accidentally grab the wrong gig bag The whole reason I bought my SX mockingbird was for him to use. It's not nearly as ugly and plays and sounds way better than that warlock. Now the serious part of the post. In a band setting do you feel it's acceptable to step in and say hey this piece of gear just isn't working. Look at trying out X item or Y item instead. Or am I just being a pompous (explitative here) about the situation. It's not like I'm expecting him to go out and get a PRS or anything but that guitar just looks and plays horribly.
