If not, the PINCH pot may not work as expected.<br /><br />In order to bias Q2 to 4.5v you should swap the 2.2k resistor (the one from emiter to ground) with a 5k trimmer. I really recommend to bias this thing.<br /><br />That said, the 4.5v are with the PINCH pot fully counter-clockwise. I ended up biasing at 3k.<br /><br />Good luck guys!Antoniohttps://www.blogger.com/profile/15088749141506941654noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-61150775796828566262019-03-23T10:53:42.251+00:002019-03-23T10:53:42.251+00:00Thanks a lot for this layout!

I run isolated power through pedal power2 and daisy chained power through boss tuner. through my isolated power there is a hum whenever its plugged in, and when I turn up the volume or gain it starts to get a tremolo sound to it. but whenever I use the daisy chain the pedal works fine. I have checked the pedal power and it works well with other pedals, any advice would be greatly appreciated. thanks simonhttps://www.blogger.com/profile/05685781929085690978noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-51374202409970027172018-01-03T22:42:49.640+00:002018-01-03T22:42:49.640+00:00Hey, I am getting double voltage from the collecto...Hey, I am getting double voltage from the collector on Q2.

Do I have to flip the transistors, electrolytes and capacitors or keep them the same way (as they would be in a mirror figure).
