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.

Music Man Sabre II Guitar Preamp

Apparently the guitar players were feeling left out with the all the old Music Man bass preamps, cuz I got a ton of requests for the Sabre II Guitar pre. So here you go! Nice and small like the others with active bass and treble controls.


  1. Any replacement for the chip?4250 seems unavailable in my area :(

  2. You can use TL071 or another single op-amp
