My bud has a Spider 75. He says 'fix it'. When I turn it on, and plug a guitar cord in, it sounds like it is connecting to a modem... crazy tones. I'm guessing its the darn digital stuff jumping into the analog. So thinks me The Old Dude, I'll just try and isolate prob to preamp or power amp. Imagine my surprise when the back doesnt reveal any preamp out or power amp in jacks. Anyone else ever heard this weird noise? Amp doesnt work. I held in button A to try to reset. Any way to operate in degraded mode (computer held in reset, no effects, just jack thru preamp to amp)?. At least that would let you finish the gig with a chorus pedal or something. Do all the factory service dudes have 4 year EE degrees? I do. Send me the link to the factory manual. If I find out whats wrong with this booger, I'll tell yall. Thanks.
