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.

BBE Boosta Grande

The Boosta Grande is a simple opamp-based boost that's pretty similar to the MXR Micro Amp. Only differences being where the pot is in the circuit and component value changes. Offers up to +20dB of boost. Should fit in a 1590A if you don't board mount the pot.


  1. It works well without problems has a decent gain, but the gain of the MXR Micro Amp is at least twice as much, I think it is not this time, I replace my clone of Micro Amp.
    Thank you! By the excellent circuits, I hope you continue for a long time.
