Re: Volume Pot in RG2550z - looking for improvement
I replaced stock pots on my rg2550 with bourns pro guitar pots (black sealed plastic body) and they are awesome. Cost about 12$ which is a bit steep but totally worth it. Very smooth taper, makes volume swells very nice and gradual. It will never get dusty because it's sealed and it's got plastic element instead of carbon which is less noisy and more durable.
You'll only need to widen the hole on the pickguard for a mm or so to fit them
Another thing to have in mind is that strat has about a fifth of power of your RG and pushes the amp into overdrive much, much later. It's easier to do volume swells with less powerful guitars.
