This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

Green Citrus

Here's a cool DIY design of a Green (Mutamp) amp emulator. Four JFET stages with a 2-band EQ and a Boost control. Should be a nice easy fit in a 125B with the board mounted pots. Here's the schematic for reference. Sound demo here.

  1. This can be tagged verified. Built it on perf and it fired up straight away. After biasing the jfets, this thing is killer

  2. Is there any way to use it as a head?

    1. It's really just a drive circuit. You could run it as a preamp I guess, but you'd need to integrate it with some sort of power amp to make a head. It'd be a pretty one trick pony though.

    2. Si puedes, sólo tienes que hacer lo que te dicen arriba. Eso o conectar la salida del pedal en el "return" del cabezal que estás usando, así puenteas el preamp que traiga de fábrica y sólo utilizar la etapa de poder.
