Hey TBers...thought I'd post this and get some thoughts from you guys...I'm gonna call the amp repair shop tomorrow and ask them the same questions. Here's the gear: GK 1001RB-II in a SKB case, and a 410SBX cab. So here's the general info: I've been touring for a while now, on the road, having gear in a trailer...basically my amp and cabinet are getting the usual road wear. Here's the backstory: My amp died on me right before a gig, about a month and a half ago. I took it to the repair shop and they fixed it, saying the problem was the bridge rectifier dying - so the AC power wasn't being converted to DC power. (Warranty covered until November '09, by the way) Here's the current problem: Anyway, I took the amp home and plugged it in to my speakers, to make sure it worked, power-wise (my bass was at my girlfriend's apartment). Well I turned it on, the clip light went on for a split second, and instead of having the power light turn from red to blue, it just stayed on red. I turned it off right away, and then tried it four or five times....the light stayed red. I was pissed, because I had to go on the road for another week without an amp. So I return after a week, and just to check it again, I plug the amp in and turn it on (without the cabinet plugged into it). Lo and behold, the blue light comes on. So I plug the cabinet into it and try again. Just the red light. I try it again and again, same result...but suddenly, JUST as I'm turning it off, the blue light blinks on. So I turn it on again and the blue light comes on (along with a little popping sound in the speakers right when it turns blue...not a scary thing, just the sound of the "door opening" i guess you could say). So I FINALLY get a chance to plug my bass into it today, and it works...however there seems to be little clicking noises, pops...I can't tell if it's the amp or the pickups, or cables, or speakers, or whatever...it's little things that will make me paranoid, but might not be anything major.... Anyway, here's my question: The amp DOES work...should I take it on the road and just play it and see how it does? Should I take it back to the repair shop just to be safe, even though there might not be any problem for them to fix? Just venting and seeing what people think...thanks for reading this long post if you made it this far!
