Hey guys, I just acquired a Marshall 6100 30th anniversary head in a trade for my Randall V2 ninja. The volume knob on the crunch channel pops/crackles when you turn it and from what I've gathered the pot needs cleaning. The problem--I have no clue how to go about this. I'm very noobish when it comes to troubleshooting/repairing amps outside of changing fuses or tubes.

So, how do you fix a scratchy pot on your amp?

It's just dust, blow it out. Or it could be a soldering joint, but I'm keen on dust.

get a tech to check it out, i forget what exactly but scratchy pots is caused by the wrong type of current reaching the pot

i don't think compresed air or contact cleaner will work, the pot is completely enclosed

for dust to bother it, the dust would have to get between the sweeper and the resistor inside of it and all that is completely closed up
