Hey there everyone, I'm new to the talkbass community and need some input regarding a problem I had with my Aguilar DB 359 at band rehearsal on Saturday. bear with me, this may be a little long. Basically, the amp cut out on me about ten minutes into our first song. It didn't completely cut out, but there was a dramatic loss in volume that made the amp unuseable. The weird thing is that when I tried my amp at home afterwards, it worked perfectly. FYI I have a passive Fender jazz bass and I was plugged into the passive jack. I called Aguilar and, although they're very nice and responsive guys, they weren't too helpful. Their tech guy told me that unless I could recreate the problem, neither they nor an authorized repair technician could fix it. Is this right? The tech guy also made some bizarre recommendations about recreating the problem, such as inserting a "chopstick" into the active input jack while playing in the passive jack and -- get this -- giving the amp a good smack. I did not do any of these things, of course, but I did try to recreate the problem at home by playing at different volumes, settings, etc.). I couldn't get the amp to cut out no matter how hard I tried. I have a gig coming up and I need the amp to work, period. Some additional history that may be helpful: About two weeks ago I sent the amp in for warranty repairs for a problem I was having when I ran my bass through my Sadowsky preamp into the active jack. When I did this (which I rarely do because the Aggie is so rich on its own) I was getting an annoying static-like sound out of the speakers. That problem was diagnosed as "intermittent contacts in the passive jack switch," and as far as I know the problem was repaired (I ran my bass through the Sadowsky preamp after receiving the amp from the warranty repair people and it sounded fine). Whether the "intermittent contacts" problem is related to the drop in volume I experienced at band rehearsal, I don't know. I would appreciate any insight you guys may have. I just cannot accept that there's no one who can figure out what went wrong unless I can recreate the problem (BTW I don't have an avatar or profile info because I'm a computer idiot and don't know how to do those things, so help in those areas would be appreciated as well).
