    ok help me out my bass friends, using an Aguilar Tonehammer 500 with a Tc Electronics 2x12 Cab. I have two basses for this show a Fender Pbass Elite and a Standard Jazz Bass. When i use the pbass the amp starts to push hard and crackle when in active mode, a compressor seems to help but i dont wish to rely on it. it doesn't crackle with the jazz bass. Can anyone help out? its probably something silly haha.

    "Crackle" or distortion?

    Crackling is more the sound I equate with a short in a cable or pickup wire. Distortion is something I equate with a signal being too hot....or batteries going dead in an active bass.

    Try both basses with another amp. That way you can make sure the problem is in the amp and not the bass.

    Cheers, i definantly mean distortion, can be the batteries cause I only just replaced them for this show im doing. I have used other amps with it and alot of the time i get the same result.

    That might indicate the problem is with the P, not the amp. It may not be that the signal is too hot, but that there is a problem with the electronics in the bass.

    Turn the bass volume down. If that fixes the problem the signal output is too hot. If that does not fix it there is a problem with the bass.

    Where is the EQ set on the bass?

    The bass eq is always set flat

    My Dingwall is 18v and has an extremely hot output when played in the active mode. Depending on the situation, very often I have to turn down the volume control on the bass and/or engage the input attenuator on the amp. Sometimes switching to passive mode is best, especially when recording direct.
    Let us know how it works out for you.
