Paul Trombetta Designs Bone Machine

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
I've added a second layout with the new extra switch but it's all guesswork.



Visual Sound Jekyll & Hyde

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 uses a Multiplexer Switching daughterboard.
The result should be a much smaller pedal compared to the original.
You can check Strassercaster verified version on the forum section.
Schematic and original thread from FSB are available here.

Madbean Tapanator Projects

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.

Madbean Cave Dweller (2015)

Here is the newer version of the Cave Dweller.
You can find Brian's original project here.
Original info:


The Cave Dweller 2015is a total re-design of the Cave Dweller project from 2012.
While the original Cave Dweller was a simple and colorful sounding delay it had a few drawbacks;

it was pretty lo-fi, and darkened the dry guitar tone somewhat. This was due to the limitation of using only the PT2399 for both dry signal and delay signal processing. The objectives for the re-design were to improve the quality of delay and dry guitar signal without requiring as many parts as a full-fledged delay circuit such as the MBP ZP Micro. This is accomplished by introducing a new input stage for dry signal processing and also by adding additional filtering to the delay signal. The result remains fairly low in parts count without compromising on the delay tone.
