Torus Hideout - Misc stuff

Spice:

• LM3900 Spice Model / Subcircuit for LTSpice

PCB Layout

• Harmonic Sweetener Layout of this public Schematic. Untested!

Circuits

• Bootstrapped Single Transistor Buffer
  Sounds good. Input impendance around 1.5Meg. This is my favorite input stage for guitar stompboxes


• I'm currently design a VCA core to be used for compressors, tremolos and related stomp boxes.
  Here are some snapshots. Don't built these, they might suck big time. I haven't done listening tests yet.
  
  
  • First Version Built from CA3046 + Opamps. Inspired by René Schmitz VCA-design. Transfer Curve
    
    
  • Second Version Basically the same as above, but with Voltage to Current converter based around 1/4 LM3900
