Seppuku Fx Memory Loss - alike
Based on the Seppuku Memory Loss - alike
From the post
The layout is based on a quite diffucult-to-read schematic found at Mod Wiggler forum. It may contain some errors and there are few question marks next to some of the pots and one of the caps, so some "trial and error" might be necessary to get this thing working as it should. Also, the "Filter" switch looks like a feedback switch for the LM386 IC and it appears to be a panel mounted push button switch but I guess a SPST toggle switch can be used as well.
Schematic
This is a board layout, a drawing of where each part goes, and the post may link the schematic it was drawn from. Open the layout at Dirtbox Layouts. No KiCad fragment has been drawn for this circuit yet.
