So, I’ve adjusted the gain pot to its maximum. The sound is improved, but still no where near unity gain. The sound, though better, is still pretty useless at this level. Should I look into increasing the value of the trim pot? Maybe a 250K or higher? Or, I was thinking I might wire a guitar pot in temporarily, adjust it to where I get the sound level I like, and then hard wire a resistor of the corresponding value – kind of like biasing an amp, I guess. Unless anyone has a better solution, I think this might actually work. But, hey, I’m no expert at this stuff.
