Has anyone here used a trim pot to set-and-forget the gain on their onboard blaster? If so, which pot did you use, and more importantly, where did you find it? Or is the preferred method to use a resistor instead? Any input would be greatly appreciated. I have a GGG blaster and have been using a 50k reverse log pot(IIRC) that is disguised as a tone control for the gain, but am starting to think I can live with the blaster gain being fixed if I can have the second tone control.
Haven't done it, but these are the trimpots we use in pedals:
