    using a gk mb fusion with a gk neo bass cab, and for whatever reason i get an ugly sounding crackle whenever i play a note. problem must be with cab, because it sounds perfectly fine when di'ed thru the amp head. file is the di first, then the cab recorded thru a mic

  2. Methodically check all cables involved, make sure your bass pickup's 9V is fresh (if active electronics), double check amp to cabinet compatibility. The cab might be just fine . . .

    this is a recent issue, already checked cables, and i dont see why the bass pickup battery would be a problem, as the DI sounds fine, although it has been several months since i replaced it, will try it

    Try the amp with a known good cabinet. The fault could be with either the amp or the cabinet (or cable)s.

    Is the GK's DI out before the master volume? Could be a dirty pot.

    does the cab have a horn and a control in back to turn the horn off?

    if so turn the horn off and see what happens
    that's still the only way to tell where the problem is; i mean, you're not fixing this yourself either way so you might as well take it all in to the repair place and see what they say

    Any crackling when you turn the dials?

    not inherently, its exclusively when i play a note (or more accurately when some sort of noise threshold is passed)

    Is the DI set pre or post? When set to pre, the signal is taken from just after the input jack. If it's set post, the signal is taken after the tone controls. The DI could be clean in pre and distorted in post.

    How high are the gain controls? Can you get rig of the noise by fiddling with the controls? Try turning down the gain and cranking up the masters. Also try toggling between channels A and B.

    Why are two speaker (Speakon) cables attached? Are you daisy-chaining a second enclosure?

    Yeah....if you aren't connected to two cabs....why the two speakons connected to a single cab?

    Using a speaker out as a DI? Or did I misunderstand what was written by the OP?

    Is that even possible?

    If you've got a single amp and a single cab, remove one of the amp to cabinet speakon cables and try to play notes again.
