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.

Run Off Groove Double D

Still a few Run Off Groove designs I haven't laid out yet, and this is one of them. It's based around the 4049 IC chip and features 2 channels of amp-like distortion. I've laid it out to fit in a 125B with dual footswitches. Bias Q1 to 4.5v and then adjust to taste as usual. More info, schematic and footswitch wiring diagram on the ROG site.

    1. Sabrotone has stripboard layouts for guitar and bass versions of this on his website.

  2. I had seen this circuit a while back. It might be something I'm looking for but I would want to add a tone stack to both channels. Where should I add that in?

    1. Easiest approach would probably be adding in a couple SWTCs just before the Volume controls.

      You could also tack on a couple of the BMP tone stack boards in the same place. I'd recommend using the one with the gain recovery stage.
