Recently my active Ray34's output became VERY low for some reason. I rehearsed with the school band moments before our performance in the University of Portland Jazz Festival, and everything was normal. Once on stage, I had to crank the 600 watt Genz Benz stack provided up to 10 just to be heard ON STAGE. I couldn't be heard in the audience, and was BARELY heard by the judging panel. When I got home, I put in a new 9 volt battery (active EQ), and still had the same problem. My brother (studying for his journeyman's license, so he knows electronics) and my dad (licensed electrician for YEARS) opened it up and checked the connections to all the knobs and couldn't find anything loose or faulty. The connection to the pickup was inaccessible because whoever assembled the bass stripped the screws to hell when putting it together, so we could not access the connections directly to the pickup. I have a performance on Thursday night and no bass! No clue what is wrong with it, and I would love some help. Thanks a ton!
