    I have no idea what the problem is, but my amp is doing a strange thing where it doesnt sound all the notes, some are louder than others, some are bassier than others, some are clearer, and some start quiet and get loud, and vice versa.

    Does anyone one know what the problem could be?
    I changed up the cables and tried several different basses, but its the same.

    I wouldnt mind so much but I've used the amp for a total of SEVEN gig over the past year!!!

    Thanks

    What amp is it? What cab are you using? What bass are you playing? Any effects?

    Of course more info is needed.....

    But that sort of thing is often due to a loose connection somewhere. Bad solder joint, bad cable, loose connector, etc.

    I play a mm stingray 5, original pickups and electronics. Into a gk fusion 550 head, and a gk neo 412 cab. Straight into the amp, no effects, just one cable. The 4 pin gk cable connecting the head and the cab is new, as is the cable from the amp to the bass.

    Do you need anything else?

    Thanks for the help :)

    I'd try a plain Jane 1/4 speaker cable and see if that helps

    Yeah, try a normal 1/4" spkr cable, NOT an instrument cable, and if that doesn't help, the next step is taking the amp in to a qualified amp tech.

    Bad the same problem with an Eden head I had not used for some time.
    It needed to be cleaned. As the tech put it.. Sitting idle didn't help it. For some reason it oxidized really bad. Lesson learned. Now I keep a can of deoxit handy and clean my inputs and pots when needed.
    The other thing I learned is the effects loop trick, take a 1/4 input jack and plug it in and out of the loop input/output. I've also had that problem as well ( amp cuts out or gets fuzzy sounding).

    It is entirely possible you have a bad preamp tube. The new tubes these days are not 100% reliable.
