It’s Fuzz Friday once again, so here’s the VooDoo Lab Superfuzz. Despite the name, it’s not based on classic Univox fuzz circuit with the same name. Rather, it’s a highly modified Jordan Bosstone with an added EQ section. One interesting thing about this one is the fact that Q2 (PNP) has the emitter going to … Read more
Here’s a cool vibrato effect designed by CultureJam and based on Tim Escobedo’s Wobbletron. Here’s what he had to say about it his original build doc. The DuoVibe is a two-stage optical vibe circuit than can also cop subtle phaser tones. The LFO is modified from the Shoot the Moon tremolo (itself derivative of the … Read more
Here is a layout for a classic pedal. I’ve drawn 2 versions: Vintage and Modern. There are 2 layouts for the Vintage: with and without output boost. I’ve added a boost to the Modern layout to avoid volume loss. You can find the original FSB thread here. 16/01/2017 Layout updated! I’ve changed the vintage layouts … Read more
Here is a layout for the older version of EH Black Finger. You can find the original FSB thread here. I’ve used Pedalgrinder slightly modified schematic on page 3. Some suggested high gain, some low gain transistors. Should test them both. … and the LM13700’s version:
Here is a verified layout for a quite unknown slapback-echo EH pedal. You can find the original FSB thread here. I’ve added an output boost to cover volume loss. I’ve found only one video around but didn’t sound great.
Here’s one of the earliest Catalinbread designs, the Supercharged Overdrive. It’s a pretty unique circuit with the Contour control adding in more distortion and saturation from the CD4007 stage. Laid out for board mounted pots and will fit quite nicely in a 1590B. Schematic here for reference.
Here is a great fuzz pedal similar to the Rockett WTF (which Paul also designed). A couple of capacitors are unknown. You need to test different values (shouldn’t be too difficult to find the correct ones). Schematic and original FSB thread are available here. Paul has also added a Si/Ge transistors switch to his V.2 … Read more
This is a verified layout of the Grey Version with an added Bass Boost switch borrowed from V.2 It’s basically 2 modified well known circuits in series (TubeScreamer & Shredmaster). There are 2 versions: – a true bypass version were you wire two separate 3PDT footswitches in series. – the original Visual Sound version which … Read more
For Fuzz Friday here’s an really interesting circuit from Durham that’s both an overdrive and a fuzz. As the name implies helps you get some Neil Young tones, but does a lot more than that. The input stage features soft clipping in the feedback loop of an opamp, much like a Tube Screamer. The 2nd … Read more
Here are some great new Tap-Tempo projects by Madbean. I prefer to add them all in the same post because they are meant to work together. You could use 1/8″ jack & plugs. You can find all info and his great (and cheap!) PCBs on his website here. The TapLFO is available from SmallBear here.
