Bass amp problems

68 lost souls

Hi,

I am having a problem with my Ashdown Mag combo. Heres the problem, while playing the sound levels tend to die for a while and then come back after a while, sometimes there are is a weid distorted sound for a few seconds, it usually sorts itself out when I kill the power and then turn it on again. Anybody able to help? I have a feeling it could be the speakers. It was only gigged once though it was an exdemo model.

Speakers would be a mechanical problem - tbh, what you describe seems more characteristic of an electronic problem. But there's no way to be sure of that. You really should get it checked out. What you describe could easily be any number of things, and it's very unlikely anyone here would be able to accurately diagnose it indirectly, even if anyone here was qualified to diagnose it to begin with. I don't think aimless speculation will really serve you here.

Right so Im in a bit of a jam then. Supposed to be using this in a week and a half in a gig! I'll see if I can borrow a cab from someone or something and see if it is the speakers, if it's not anyone able to recomend a good place to take her?

had a similar problem with my old 4x10" combo. if theres an effects loop, try put a patch lead between the send and return of it. the problem should be ok then, worked for me. it'll get ya by till you get the amp sorted by a professional. sounds like a wire loose.

Cool Ill give that a go.

any luck?

Tried it out today and the problem seemed to have rectified itself. Its weird, it might have something to do with the fact that I was running two amps and 4 pedals off the same adapter?

It's your pedals that the problem would have been in then. Were you using any Jiim Dunlop pedals? When the voltage drops below their lowest acceptable threshold they can do this. I've heard it, exactly what you describe. Then again, might not be. I think it was the pedals though.

I wasnt using anypedals through it when I forst noticed it. It still doesnt sound exactly right to my ear, still a bit of distortion on the lower end.The higher end of the scales and stuff sound right but when I play low notes it sounds bad.

HusseinSarhan

Just a coincidence so. I'd take it to a tech. Could be a number of things.

Oh, it's not an active bass is it? Check the battery if it is.

No its not an active bass, its a Tanglewood Rebel4k.

There's your problem right there.

well, as i said, its a temporary solution to the problem. you NEED to bring this to a tech. i dont think its anything to do with running two amps and four pedals out of one socket.

No its not a mains overload, anyway all of the sockets in a room are likely to be wired parallel with eachother so it doesnt make a difference if you plug all of your gear into one socket TBH.

Sounds like an electrolytic capacitor somewhere in the loop after going loose, charging up and discharging every now and then.

The fact that when you turn it off it solves the problem for a while seems evidence towards this. The fact that its frequency dependant distortion seems further evidence.

All the more reason that you should bring it to a pro to fix it if this is the problem (still only wild speculation:) ).

Paladin thats exactly what my brother thinks, wasn't sure about it from him cause he doesnt know about amps but he sure does know his electronics, his engineering degree proves that. Yeah Ill bring it to a tech when Im free. Orals next week.

Your bro has an electronics degree? Get the lazy bastard to look for a loose cap
