onyaw Posted July 13, 2014 Share Posted July 13, 2014 Hi - simple question i hope. The master control volume on my spider valve 112 is very crackly when i turn it (maybe some other knobs too). i was going to very lightly spray in some cleaner around the stem but I can't get the knob off and i read in another post not to pull too hard because they're right on the circuit board. how to get them off/how to clean the pots from the outside? that other post referred to a video on the site but i can't find it. thx. onyaw Quote Link to comment Share on other sites More sharing options...
takyem Posted September 11, 2014 Share Posted September 11, 2014 For all my knobs guitar , amp etc I wrap a string around the knob once or twice then gently pull up on opposing ends wiggling it loose Quote Link to comment Share on other sites More sharing options...
