Need help diagnosing amp problem!!

This subforum is about building basses, so you'll get better results in the amp forum. When you post there, you'll need to offer more information before anyone can help, for example which amp it is, how you have it connected, settings, and if there's anything else in the chain, whether you have a different cab to try the amp on, etc. Hope this helps.

Combo or amp?

Sounds like a tech will be needed.

 

Yeah, what amp?

 

+1


I would check all cables involved (from head to cab, if not a combo).. also check instrument cable.

And dont forget to check batteries if its an active bass.


That's about all I can do with pretty much zero information.

 

Is there a device plugged into the effect's/in-out loop and not powered-up?

 

Does that amp have an effects loop or power amp in? Maybe try plugging your bass directly in to the return and see if you get any sound?

 

9 times out of 10, when all the obvious things have been looked into, an amp tech is the solution.

 

do this first

 

Yes do that.
Also try a different speaker cable and try something else into the cab to make sure it is neither of those. Try a differnt bass and instrument cable too. It is a process of elimination
