Played a great gig last night with my Allman Brothers tribute band, The Allman Step Brothers. Two bands opened for us. Had a good sound check, went to eat and listened to the other two bands. Part way through our set, our singer walked to my amp and turned up the master on my GB Shuttle 6.0 and said my DI wasn't working. I told him later to just tell me to turn up rather than crank the amp. Anyway, I adjusted my amp, played the rest of the set. Breaking down my equipment, something was conspicuously absent from the back of my amp, the DI cable. The sound man forgot to plug it into my amp after the prior band. He was just a might embarrassed afterwards. I will be sure and not let this happen again in the future. Everyone makes mistakes, not a big issue, just unfortunate.
