From the post
With the G-2 fresh in our minds, I thought I'd draw up the SS-2 as well. This is set up for a 125B like the G-2 due to the footswitch board. The circuit itself is like an MXR Distortion + with a tone control and a gain recovery stage. Originals utilize 2, LM741 chips, but I've drawn it up for a LM1458 (which is a dual version of the 741) to make things a little easier and save space.
