hi
i'm asking this for my bass player. the situation is the following: a couple of weeks ago we went to our rehearsal space, plugged everything in, and started playing. in the middle of the first song, our bassists amp basically shuts down. you CAN hear a sound, but it's terribly distorted and REALLY quiet....with the volume full up. so far, so good. now, we stopped that rehearsal. one week later, when we wanted to rehearse again, our bassist brings another amp (the original one is broken, remember?), plugs in....and EXACTLY THE SAME HAPPENED. he plugged his bass in, played a note, everything alright. he played another one, and thats it, terribly distorted LOW volume sound. he said that two days ago he played a gig with this exact same amp, with no problems.
another strange thing is, that occasionally the amp switches to "normal"....and works perfectly, but only for a couple of seconds, then it will shut down again.
both amps are solid state, so it cant be tube failure.
i dont know which exact amps he plays (i think his main one is a hartke combo), but they are both 100w and 200w combo amps. but i can ask him if you need to know the exact model
so, does anyone have an idea what the problem can be?
maybe a bad power supply? although we've already rehearsed dozens of times in the exact same room, with no problems, i think it is because of the power, because my (tube) amp is way more noisy when rehearsing than at home or in other rooms in general. (the hiss is louder btw, no humming or other kinds of noise...and it's pretty much dead quiet when switching to the clean channel...the lead channel IS noisier than at home, though). but really, i'm neither an amp tech nor do i know much about electronics in general....i'm just guessing [img]/images/graemlins/smile.gif[/img]
it's a pretty shitty situation, though, because he doesn't have other amps than those two, and rehearsing without a bass player is no fun (and he is a great songwriter btw), so it's really limiting our band.
anyways, thanks in advance
