Bearfoot Emerald Green Distortion Machine
Today is Bearfoot day. Info about the original For the Vox lover in all of us, Bearfoot FX has created the Emerald Green Distortion Machine- a pedal which captures the chimey, crunchy essence of the AC series amps and provides a faithful simulation of the Vox tone through a variety of amps. Used through a … Read more
Bearfoot Candy Apple Fuzz Gold
There was a resistor missing from the schematic so the layout has now been fixed. If anyone has already built this then if you can add a 2K resistor somewhere between the germ transistor emitters and ground that should sort it out. Or you can use then fix layout John did at the bottom of … Read more
Frantone Vibutron
Great sounding tremolo here from Fran, and something for me to finally build with the batch of ICL8038 ICs I bought a couple of years ago! :o) To keep the size down and make it 1590B friendly I’ve done away with the rotary switch used in the original, and instead I’ve used a DPDT on/on/on … Read more
Son of Screamer
OK we already have this here essentially with the Lovepedal Eternity, but this was a request and using the Eternity as a template meant it took 2 minutes to do. This is Jack Orman’s circuit which pre-dates the Eternity and so the design that Sean was “inspired” by. Anyway I suppose it’s nice to keep … Read more

Fulltone Bassdrive Mosfet
And the bass version. This is based on the guitar version but with the passive changes to match the filters in the bass version. The diodes seem to have changed often in this, some with symmetrical mosfet/germanium combinations with a 1N34A in both directions and some with asymmetrical as shown here. Some with more than … Read more
Fulltone Fulldrive II Mosfet
Requested by a few people. Even at 22 columns wide it could still fit in a 1590B if you wanted, and the first person to do it wins the TagboardEffects Awesome Builder of the Week award! :o) But I wasn’t too bothered about the board size because I suspect most people will want to put … Read more
