A few years ago I had Howard Davis modify my old MXR Flanger for 18v operation through a DC jack and he calibrated it at that time also. Now that I've gotten back into live performance and put a board together I've noticed a volume drop of a few dB when the pedal is engaged. Is there something simple like a resistor swap that I might be able to do to bump up the volume a bit? Looking at the schematic I can't really determine which resistor would determine the volume of the circuit.
Bump!
Equally reduce the value of the two mixing resistors going to the inverting input of the output op amp (150 & 82k on the schematic).

Maybe start with 120K & 68K. Work down from there.
Thanks guys! Those values were bang on for getting unity volume!
