@brejna what did you do to bump the volume up from that linked post? Having the same issue. Thanks!

Currently struggling with the same on a LyRock clone build. But the resistor #s that match up with the analogman gutshot and the LyRock dont' match up with any schematic I see on line. is there a way to properly compare?

Hey everyone, my name finally came up on the KoT waitlist and I got mine in the other week. Naturally I pulled it apart to see what the famed high gain mod actually was. Turns out the drive pot is the same value as the standard but the resistor in the feedback loop changes values.

I'm attaching the schematic I came up with from tracing mine. Certain resistors in each side where carbon comp as well so I've noted that in the schematic with CC.

Hope some folks find this informative. This community has been super helpful to me so I wanted to pass this info along.

Edit: Updated the schematic to include the serial number, IC value, and fixed the clipping diodes sections.

Had a question I don't understand. It doesn't look like the R# numbers for each resistor match from your trace to the PCB numbering. is there a reason for that?
