Thanks. :-)
I was pondering making the PWM and FM1 knobs smaller yet and having them side by side and then putting the waveform selector above them and below the Coarse pot. (Coarse pot would be a 120 turn one and the Fine control eliminated) Then I could put the FM2 jack back in (with no pot) but, I honestly almost never use 2 FM inputs on my 300's and I don't want to make the panel any more crowded than it is.
Also, if I can find the right kind of switch for the waveform selector I'll be able to add a couple different pulse shapes instead of just square . . maybe 25% and 75% at least?
