Amp Problem??

Post by Tony Rankin »

I took my Nashville 400 to a friends house the other night. When I hooked up the steel and turned the amp on, I had near zero volume and at times the amp was breaking up. It sounded almost like I was using a fuzz tone at times.

When I got back home, I hooked it up. It worked fine and has worked fine ever since then. I have never had a problem with this amp and I can't figure this one out. Could low voltage have caused these symptoms? Any ideas?

This is a common problem, usually caused by a bad connector in the amp.
My solution is to hold the amp a few inches above a hard surface, and release it, but the techs here may have a better idea.

Are you sure it was the amp? Could have been a bad guitar cord. Set it up EXACTLY like you had it - cords volume pedal effects, etc. - when you had the problem, and see if it happens. Wiggle each cord to see if one of them has a flakey end, etc.

I don't recommend that you "drop" the amp! Doing this will most likely cause other problems.

Take Jack's advice first, then try to duplicate the problem and if it reoccurs, then patch a cable between the PRE EQ OUT and PRE EQ IN jacks on the front panel. If there is still no signal present, then patch a second cable between the POWER AMP IN and PRE AMP OUT jacks on the back panel. The PRE EQ IN and the POWER AMP IN are switching jacks which could be malfunctioning.

If all of your cables are found to check out good, then I suggest that you take it to a qualified technician.

I'll be glad to assist you further with other possibilities. I can be reached toll free at 1-877-732-8391.
