hello,
i fixed my PT-80 and it sounds very nice indeed! There is a soft whistling coming from it however I do not have it in an enclosure so i'm guessing thats the culprit, other than that, no noise whatsoever!
anyway, I would like to add an SPST switch to this circuit to kill the dry sound. I was told I needed to place it at "A" on this schematic:

Which I see is coming off the TL072 into a 10K resistor, but I am not sure which one of the two it is on here:

Once I find out which one it is, i should simply intercept the signal off the opamp and place teh switch between the opamp and 10K resistor, right?
Thanks so much!!!
PS-what is the approx stock delay time of the pt80 at max time?
The arrow in the picture points towards the lead of the 10k resistor you have to lift.

why thank you very much Andre! I had suspected that was it, but...I was not sure. Thanks again.
