ibescotty Posted July 22, 2003 Share Posted July 22, 2003 Total loss of sound!!! Well this Saturday I lost sound from my rig on stage in the middle of a song. Everything was just gone. Lights were on, and things were plugged in but there wasn't anything coming out of the speaker. The band finished up the song and I acted out the rest of the song but there was nothing there. I frantically went over my rig trying to figure out what was going on while the guys told jokes up front. I actually plug 2 bass guitars into my amp. One in the -15 db and one in 0db. I turn down everything on the one I'm not using. In fact I only ever use that guitar maybe once or twice throughout the whole set. Well I unplugged that guitar and turned off the amp for a few. When I turned the amp back on everything was fine. I played another 2 sets with no issues. So either that second guitar was messing things up, which I can not duplicate or the amp over heated or something. It came right back though. It was very strange and I don't want it to happen again that's for sure. I mean there was nothing there but everything was plugged in and fine. Neither guitar worked so I guess it had to be the amp. Maybe it's time to shop for a new rig. Wait that's a good thing!!!! Double Posting since March 2002 Random Post Generator #26797 Link to comment Share on other sites More sharing options...
MasteroftheGfithfretDstrin Posted July 22, 2003 Share Posted July 22, 2003 Let me see... Are those active basses? Check the batteries in that case. Check the cables between the head and speaker if it´s a stack. That´s what came to my mind... Another time, pehaps. But we´ve got very nice pies though...

davebrownbass Posted July 22, 2003 Share Posted July 22, 2003 Well, I can't remember what amp you got, but many have thermal overload circuits. Were you loud, amp running hot? If so, that circuit kicked in. Shut down, cool off and it comes back on. I would take the precaution of running a small fan at the cooling vents of the amp. Couldn't hurt.

ibescotty Posted July 22, 2003 Author Share Posted July 22, 2003 One bass is active and one bass isn't. The bass I don't use often has the active pick up. I wasn't playing it at the time. Even if the there was a problem with that it wouldn't take out the other bass. I wouldn't think so at any rate. I had the amp at about 60% all night. I think I'll turn off between sets as well as the fan suggestion. As for what my rig is? http://www.chrisguitars.com/crate-b200xl.jpg This isn't it but this is the exact model. It's not much but it's served me faithfully for many years. I've been wanting an upgrade actually. Just haven't allocated the funds as of yet. I've been gigging a lot lately so maybe it's time to retire it. Double Posting since March 2002 Random Post Generator #26797 Link to comment Share on other sites More sharing options...
davebrownbass Posted July 22, 2003 Share Posted July 22, 2003 Don't worry about the basses...that's not the problem. What brand is that amp? Hartke? If so, it must be very old. I'm still thinking it's an automatic thermal overload...you ran it too loud and too hot. Notice on your pic that there is no cooling vent on front....perhaps you had that back shoved against a curtain or something so air wouldn't circulate.

ibescotty Posted July 22, 2003 Author Share Posted July 22, 2003 Actually it's a Crate. It was a huge stage and the back of the stage was elevated. I had my cab on the back wall but the amp was on the floor by the edge as I was on the lower part of the stage. The back was wide open. It was a very hot and humid night though. Maybe the heat just got the better of it. It's probably mid 80's vintage. It's always worked great. I'll just have to be more carefull with it.

davebrownbass Posted July 22, 2003 Share Posted July 22, 2003 I did a search, and found that there is a tech site that lists this amp as having "intermittent output probs." Unfortunately, you have to subscribe to the service to go any farther. Here\'s the link. A single instance of failure would preclude me from ever using this amp onstage again! It would become my teaching amp. Now, that being said, use the amp, but guard against overheating. If you want to find someone to look into it, fine, but I'll bet there are better ways to use your money than chasing down a problem here.

ibescotty Posted July 22, 2003 Author Share Posted July 22, 2003 Wow thanks Dave!! Yeah there's very little money invested in it but I'd rather not have to deal with this type of thing. Time to get a new rig. Eeek!! Double Posting since March 2002 Random Post Generator #26797 Link to comment Share on other sites More sharing options...
Lawnmower8 Posted July 22, 2003 Share Posted July 22, 2003 Fans, fans, and fans. Overheating = bad for any amp. Find a way to cool that puppy if you're going to continue to gig with it. "Tea & Cake, or Death!" Link to comment Share on other sites More sharing options...
