    Pulled the pre out of my GSR205 (L) wired as VVT and now both of my pots scratch and then scratch loudly (almost a POP!) at full volume.

    Am I missing something? They didn't scratch before and its loud enough to trip my limiter on my wireless.

    looks normal at first glance.

    might just be dirty/worn pots that need to be replaced, or at least hit with some contact cleaner.

  5. Could you have fried the pots with the soldering iron?

    I'm waiting to get some cleaner, I just found it odd the way they suddenly do this. This is my daily driver so its not like I'm just now noticing this.

    I didn't hit those with the iron.
     
  7. For cleaner get Deoxit and only use the smallest amount necessary.

    Found the problem!

    Ok, I got the DEOXID and cleaned up the pots - no dice.

    However, while I had the cover off I pulled the wireless off and used a hard line and - no scratching!! So I checked my wireless transmitter and I had the mic/inst switch bumped to mic. Moved it over to instrument and WOW! No scratch and my tone pot came alive! I didn't mention that before as I figured it may have to do with the pre coming out. Everything seems more responsive than when I had the preamp on (probably in my head though).

    Thanks for the suggestions everyone.
