Update on the circuit.
The sound has improved allot in the low end. C2 and C3 are at 10uf. C1 is at .01uf. R6 and R5 are now 220k. R2/R3 are 1meg. R1 is 470k.
The main purpose of this circuit was to have a A/B box with a adjustable 10db boost at each output, not to drive long lines, well at least no more than 10m. The boost was intended to be used musically, ie: to drive the input of a amp harder.
For all intensive purposes i could add a third TR output, then add a cap between the op-amp out and the jack.
