I have the luck to be blessed with very few failures of equipment. Thinking about over the last 40 years I've played I've only had a couple pieces of equipment fail. And only 2x during a show. The two show failures were a Boss Bass chorus pedal that died and a Peavey PV 1500 that overheated (but came back on when the thermal fuse reset, lesson learned in that one) Last summer I ran sound for a local event and played in a couple bands that were in the lineup so I had my Rig as back line, During the show my rack vibrated off the 6x10 cabinet and crashed to the concrete pad. The Peavey DPC1400X died in the fall (swapped out the power Amp during the show, Peavey since repaired) but the (all tube) Ampeg SVP-PRO survived the 4 foot fall without damage and its still in my main rig. My only other failure was my first Ampeg SVP-PRO and that was at home during practice, the secondary winding for the HV to the tubes in the transformer opened up. Part no longer available. I have since then added small cooling fans in both of my other 2 Ampeg SVP preamps. Otherwise I've been very lucky as I see a lot of threads with Amp failures. Tell me your horror story, equipment failure and how you finished the show.
