Madbean Turnabout (JHS Andy Timmons)
Brian’s take on JHS Andy Timmons pedal. This is not an exact clone of the original circuit and the video is for reference only:

Wampler Faux Spring Reverb
The Faux Spring Reverb, like many pedal reverbs is based around a Belton reverb module. Originally it used the BTDR-1 (which is massive), but in this layout I’ve adapted it for the newer and smaller BTDR-2H. I’ve also simplified the power section a little, and used a TL071 for the second IC. In the original … Read more
Madbean Wigl (Vibe)
Brian’s take on John Hollis Easyvibe. You can find his 1590G size boards on his website. Check his original notes here for more infos on how to build this project! Here is another version with Mark Hammer’s anti-ticking mod as suggested by Ciaran:
Death by Audio Evil Filter
Here’s an unreleased version of the Evil Filter. It’s similar but not quite the same as the original. The schematic was pulled from a video interviewing DBA’s Oliver Ackermann and was redrawn here. Some of the parts are a little pricey but the resulting sound is apparently amazing.
Zvex Fat Fuzz Factory
For Fuzz Friday, here’s a layout for the Fat Fuzz Factory in a 1590B in a more traditional orientation. All pots are board mounted as well as the Fat Switch. For C1 and C2 you’ll probably want to experiment with values. Using an on/off/on switch gives you an extra option over the original. 3.3uF is … Read more
Madbean Glam (Chorus)
Here is Brian’s new PT2399-based chorus. You can find all infos from his website here. Here is a video by Ciaran:
Mad Professor Stone Grey Distortion
Here’s the Stone Grey Distortion from Mad Professor. It’s reminiscent of the Distortion +/OD250 circuit, but with a hex inverter stuck after the opamp. It also uses 2 JFETs in the feedback loop of the opamp for clipping. Original op amp is the TL051, but other single opamps can be used (Tl061, 71, etc). Should be … Read more
Madbean Fencepost (Noise Gate / Expander)
Here is Brian’s version of Armdnrdy’s project from the DIY Forum. You can find the original thread with all the infos here and Brian’s version here.
