Bad pot...or not?

    I have a 2005 Cirrus BXP-5, that I received this past November. I'm the guy if anyone remembers had the low battery life that ran out super fast, but anyway, when I got my bass, I noticed the 5th knob, or the blend knob, crackled when I turned it while playing. As time progressed on, month after month, I noticed it crackled more, louder, and then it began like making my sound become SUPER QUIET...and then all I would have to do is rotate the knob just a tad and it would pop and then the normal volume would come out. Then soon later, I could strike a string, and rotate it, and the volume would go LOUD soft LOUDDD soft LOUD as I slowly turned the knob clockwise. And as of now, I think sometimes it makes the bass have no volume, and then when I turn it then the volume suddenly kicks in. What the heck is this problem? Cirrus sent me a new pot, but I just havent gotten around to replace it. Is this what the problem is? Anyone know/had this problem before?

    Definitly sounds like the pot is the problem.
    Haven´t had that problem on a bass, but with pots in other electrical circuits.

    Definitely sounds like dirt in the pot..... sometimes, just a little contact cleaner (the kind WITHOUT silicone in it) and work the thing from stop to stop about a hundred *yes, a hundred* times, and it might be OK.

    My son's December 2005 MIA Cirrus 5-string has the same problem with the blend control pot. It's at the local Peavey dealer as I write this post. The problem began exactly as you described but progressed until there was no output. First trip to the shop they checked the solder joints and cleaned the volume pot; thought they had fixed it, but it came right back. Now they're saying they'll have to replace the electronics. I'll keep you posted.
