If none of the inputs work, then you may have lost part of the power supply. DO NOT go into this amp under any circumstances !!!!...there is enough voltage in here to kill you crispy !! I would strongly recommend that you take it to a respected repair shop that specializes in guitar amps. Possibly visit the ampeg website for an authorized repair center. It might cost a few bucks, but the Ampeg is highly sought after by musicians everywhere !!!....thanks... Rob

On my Accustic B30 bass amp the input jack is not working. Can this be easily fixed?


Have you checked the battery? Put a brand new one, if that's not the problem, take it to a reputable tech.

Relay?? I've never seen a guitar or bass amp with "speaker protection relays"...usually they're either on or off. Check the simple stuff 1st...is speaker cable from head to cabinet and/or the input cable from bass to the amp good? Check the "Direct Out" for a line level signal (must be connected to a PA or other amplifier) as this is your preamp out signal. Also, plug a shielded cable from "Effects Send" to "Effects Return"...this will verify "effects" loop issues if any. Lastly, vibration test...use a clenched fist across the top, sides and bottom of wood cabinet to lightly "jar" the internal circuits. If it starts working even for an instant, I would suspect intermittent connection inside.

The input hole where i plug in my bass ripped off. is there any way to reattach it?


When I have repaired damaged cabinets, larger "fender washers" of modest thickness usually work the easiest, and look the best.
Otherwise 2 chunks of clad board that span the hole on either side of the panel to make a sandwich and drilled to accomodate the jack will work if the old panel is thin enough. If not, one chunk can be used and then that patch of a single clad board gets attached to the panel with screws..

The CD input on my Ampeg BA 115 works, but the 0db and -15db inputs don't. This happened immediately after using the CD input. Quick fix, or repair shop? Thanks.


Hello,

Sounds like a repair shop job to me. Inputs on a amp have resistance thus there must be a issue inside hence 0DB to 15DB if you go higher well that input thus would not work anymore.

Repair shop would be your best bet for this amplifier. Quick Fix would be unplug it and plug it back in and praying it resets but that won't happen.

hope this was of some help, if not I am sure others will chime in with there 0.2 cents.

Regards

Brand New Ampeg Ba 600 210. Only Used durin 2 shows. Sound is awesome. Go to use it this weekend and absolutely no sound at all coming through the speakers. Compression, eq and Everything else working when...


Another person posting on here I suggested opening his unit and he had blown speakers. I think these that are DOA after previous use may be blown during the previous shutdown of the amp driving them and those with built in amps are blown when mixer is powered down putting out a large pulse. Hopefull the amp is blown rather than the speakers... cheaper to repair. Open and check for a fuse, but dont' replace it until you find out the cause of it blowing as additional damage can occur.

Clip light is on even when no input and when bass is plugged in input low volume and distortion at speaker output


One half of the power amp has failed. You can damage the speaker... do NOT use this until repaired.
