Just kidding. I do, however, have a related question. I've heard this both ways, and I'm curious what you guys think. So a drummer buddy of mine comes up to me, talking about a gig he did last night with another bassist I know. He says she was using the backline amp (which I was getting ready to use this afternoon while he was talking to me), and the cable provided to link the 60W Ampeg head to the 100W Ampeg 4x10 cab was an INSTRUMENT cable. He says the cable caused the head TO FAIL, and so they went to the local music store after rehearsal and before the performance and picked up a SPEAKER cable. No problem after that. Got me thinking - does it really matter? My understanding was always that higher gauge cable is great for preserving the powered up signal, but will it actually damage an amplifier to use instrument cables to carry the power? I've been told "yes" and I've been told "no", both by music store employees and musicians. Granted, on all my PA gear, I cheat to the side of caution and like the feel of the higher gauge cables anyway, and my bassist recently switched to a high gauge cable on her rig for the same reason, but I'm interested to know if there is actually a danger to the equipment. Is there a wattage ceiling where damage is more likely?
