O.K I built this unit using a 6.3-0-6.3 trans (taped off the CT). Measured 14.95v on the secondaries of the tran. The end result is 8.8vdc. Is this enough for most pedals or should I aim for 9 - 9.5v by playing with resistor values?
8.8 sounds good to me.
I'm not very experienced with pedals and their voltage requirements. Does voltage affect tone at all with pedals?
Some say so, moreso with older analog pedals. Back in the '70s I used to think my old Crybaby sounded sweeter after midnight when my battery had drained a bit. Coulda been the Miller effect though!
