So I've decided id like to add an output trim to the ml12's I am building. I'd also like to possibly add a stepped gain switch. I've researched a good bit reading various 312 threads but I'm not sure how I can implement this on the ml12? Could I just use one of the gain switch PCB's and grayhills that CAPI sells replacing the 25k pot? Where would I tap for the output trim? A point in the right direction would be great. I'm not positive about the gain switch but I'd like to explore my options and also it'll help strengthen my understanding.
