Layout updated. If you want to build this now I would suggest you build this version http://tagboardeffects.blogspot.com/2014/02/keeley-katana-boost-layout-rev-2.html Vero layout for this popular pedal with built in charge pump to provide the required 18V from a 9V supply. UPDATE (09-02-2012): The schematic that this layout was created from has been shown to be incorrect. In … Read more
A few people have requested a vero of the Mastotron, so here it is. If you want to make it verbatim then you would put a 100 ohm resistor in series with the input wire before the pot, and a 100 ohm resistor in series with the 9V supply wire, but I personally wouldn’t bother … Read more

Another great sounding overdrive Quite a few people have had issues with the circuit oscillating with presence and gain maxed. This has been known to happen more easily with some pickups, while there hasn’t been an issue with others. Usable cure has been to put a buffer in front of the circuit to isolate the … Read more
