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 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
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.
Here is the newer version of the Cave Dweller. You can find Brian’s original project here.

Here’s a really nice delay designed by Nocentelli. You can find the original thread on FSB here. This is his description of the circuit: Here’s a variation on the deep blue delay; two PT2399 chips and a current mirror delay pot give around 2200ms delay, although beyond 700ms gets pretty lo-fi. There are two points … Read more
A dual overdrive based on the classic grey spec DOD 250. The schematic didn’t come from the original EQD pedal. David has recreated the circuit on his website (Perf & PCB Effects Layouts). You can find his original and verified layout here.
Up next in the tube preamp series, I give you the Orange AD200B MkIII. This is the current production AD200B, which has a few changes compared to the MkI, which is why I figured it would be a good idea to make a layout for this version as well. Similar to the MkI, the MkIII … Read more
