I am replacing my warwick 2 band MEC pre-amp. I am putting Delano sonar that has 3 bands. I wanna use stacked pot for bass/treble for avoiding drill one more hole. Delano uses 50k pot for each band control. There is no 50k/50k stacked pot. Can 250k/250k(or 250k/500k) also work instead of 50k/50k stacked. Sorry for my english btw.
