try applying WD40 on the pot
If the GCB-95's pot is a Hot Potz (most likely) or some other kind of sealed pot, you won't be able to spray any kind of contact cleaner into it. Otherwise a good suggestion for remedying scratchy non-sealed pots.
I got a Dunlop GCB-95, yung bang pag maglalagay ka ng battery kailangan buksan mo ang apat na screw. I bought this around 1994, scratchy na ang pot at minsan ayaw mag-engage or disengage.
My question is:
1. Kanino ko pwede ipaayos? Mga magkano aabutin kaya? Locally available ba ang parts? I'm planning to sell it if it will cost me too much in the end.
2. Ano difference nito sa isa pang GCB-95 na iba na lalagyan ng battery? Yung merong battery terminal na sa labas, yung tipong di mo na bubuksan pa ang cover. Mas luma ba yung sa akin? Aside from the battery placement, same components ba sila? Same sound?
Thanks in advance!
If you want to add an easy-access battery compartment, you'll need something like this:

Or, you can get a battery door -

I suppose you can replace the pot with any standard 24mm d-shaft pot, 100K linear or audio taper, although the taper might not be the same as the Hot-potz (i.e., the treadle response would be different). Otherwise, get one of these pots:

You can try one of two things: 1) replace the worn out pad with something similar, or 2) raise the switch (this will require some disassembly).
I know some of the forumites here work on pedals, BAMF, Emil_Murillo, and I think qwi does too. Check with them.
