Hoooooray. The misioncontrolherniamaker is feeling much better. The problem has been solved, and Mr. Butler's diagnosis wins the prize for being the closest to the strangeness that was actually going on. The speaker outs were jumpered to jacks on the side of my rack. The jack grounds were weakly and intermittently shorting through some metal components of the rack. When I attempted to contact Electar*, Gibson Tech Support wanted me to send the unit away for repair by an authorized service center. Since I wasn't at all positive the problem was within the amp at all, I really just wanted some assistance in troubleshooting its use with other equipment. I can understand Gibson's perspective in wanting to ensure the problem wasn't on their end with a defective product, but I really didn't want to pay to send a new, straight-outa-the-box amp away for repair when there probably was nothing wrong with it, to find a problem with a larger system of which it was only a part. Gibson's Tech Rep was polite and professional, and I'm not slamming their service at all, but I feel fortunate for forums such as this one where a common topic of discussion is the INTERACTION of the various pieces of gear within our setups, not just manufacturer-specific specs. It's cool that reps from several different gear-makers can exist symbiotically on Looper's Delight, enriching the loopcommunity as we mix and match our electronics, new and old. In troubleshooting, I found several other weak links in the system, which have since been addressed, so in effect my whole speaker system has just had a tuneup. Sounds pretty good now! Amazing what a little solder, a vacuum cleaner and some replacement grille screws can do to a club-weary pair of 12" stage monitors still wearing the dust and grime of their tour of duty in the Elvis Room, Portsmouth, NH. Thanks to all who offered advice. Tim * Didn't a batch of EDP footswitches come out a while back bearing the Electar logo? What happened with that, anyway? How many divisions did Gibson shuffle it around to post-Oberhiem and pre-Trace Elliott? The manufacturing history of the EDP would make an interesting addition to the Tools of the Trade page for the EDP, don'cha think?
