I played a gig last night, where I let all the bands on the bill use my cab. The first band also used my head, which wasn't a problem. The next band used their own head (one of the new Orange bass terrors). Whilst they were playing, I noticed there was no sounding coming from the cab, only through the DI into the PA. When it came to us playing, I saw that he left my head plugged into the cab whilst his head was too! I couldn't get any sound to come out of my cab, other than a weird pop on the E and B strings, but it was coming out fine through the DI.
I was just wondering if this would've caused something in my head, which I'm guessing is the most likely, or the cab? I don't have another head or cab to test out either.
Either way, I'm hoping he's going to be decent enough to cover at least some of the costs, although he didn't seem to keen on the idea at the time!
Cheers guys.
