Tube-Town Effects
Based on the Tube Town Effects
From the post
Here is a serie of tube effect pedals by the German Tube-Town which were requested a while back.
There aren't videos available but you can find all infos, schematics and pcbs on their website here.
(The Pepper Shredder has been discontinued but it's supposed to be a tube distortion based on the Twin Valvecaster)
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 Tagboard Effects. No KiCad fragment has been drawn for this circuit yet.
