Devi Ever Dark Boost

Haven't done a Devi circuit in a while, and I keep stumbling across them, so here's the Dark Boost. It's essentially an Electra circuit without the clipping diodes and a Pre-Gain control. Apparently works pretty well on bass too.

  1. Sorry if this is unrelated.

    I have drawn the schematic for Diezel VH4 based on FSB. But it is quite challenging for me to lay it out on a single layer as they are big.

    If you guys want to help with the layout, just mail me at syamilaliff@gmail.com

    Schematic was drawn using Diptrace.

    1. Yeah, anything higher hFE like 2N5089, BC549C or similar should do the trick.
