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.

Tiger Pre-Amp

If you're a Dead Head, you'll probably be interested in this one. It's the pre-amp from Jerry Garcia's Tiger guitar used from '79-'89 and built by Doug Irwin. It's a unity gain buffer to prevent signal loss with long cables. It can be built into a guitar like the original or into a 1590A. Other single op-amps can be used instead of the LF356N (TL071, NE5534, etc).


  1. Verified.Transparent unity gain buffer is it.I have socketed input and output caps to experiment some values for my bass.

    1. You could, but it's designed for the output to be at unity. Not going to get extra gain out of it.

  4. That is not unity gain and the diode you added, was not added for a reason.
