I built and installed a VPM-1 kit and it is working fabulously. I now have it in the effects loop chain of my Fender Hot Rod Deluxe. If I set the volume pedal at it lowest volume before the sounds starts breaking up, I can turn up the preamp on the amp for a really nice sound at a quiet level. What I would really like to do is turn the gain setting on the pedal way down so that I can get the same effect and use the full range of the pedal. I have not been able to fine schematics for this pedal. Is anyone able to share information on what mode could be done to turn the output gain down another 10-20 dB?
