GoosoniqueWorx Seventh Heaven
Got a request for this one. It's apparently a modified Bogner Ecstasy Red, which is a JFET adaption of the Red channel on the Bogner Ecstasy amp. Since it uses 2 footswitches, I went ahead and designed...

BearFoot FX Honey Beest
This one just got traced over on FSB. Apparently the heaviest of Bjorn's Honey designs. Here's the schematic for reference. Note: In the schematic the source and drain on Q1-2 are reversed from the way...

Ramble FX Marvel Drive 2/3
Here's a newer version of the Marvel Drive from Ramble FX. Did the first version of this circuit a couple years ago, and decided to update the layout with board mounted pots and the Presence pot. I...

Baja Optical Limiter
Here's one of Bajaman's non-amp emulating circuits, the Optical Limiter. It's based on the Demeter Compulator, but is not a compressor but a limiter. What's the difference?The ratio is the main...

Mini BassDrive
This is an adaption of the Fulltone Bassdrive without the boost footswitch, allowing for a smaller enclosure. I got the idea from a comment by Simão on the Fulldrive 2 post, and I though it could prove...

Function F(x) Clusterfuzz
This Fuzz Friday I present you the Clusterfuzz from good dudes at Function F(x). It's a great sounding fuzz and really versatile. You might be able to squeeze this into a 125B if you can squeeze the...

Menatone Pig
Came across this one and it's an interesting JFET-based OD with active bass and treble controls. It's apparently based on a late-60s Marshall 200 amp. Drew up the schematic for reference.I believe the...

Caline Mark 4
Got a request for this and an interesting circuit. Apparently it's a simplified version of the MI Audio Tube Zone. Should be a good jumping off point for modding. Schematic on FSB.

Basic Audio Spooky Tooth
Found a trace of this over on the Tagboard Forum. It appears to be a highly modified Fuzzrite with an added gain recovery stage and a lot of value changes. The Saturation pot increases the output cap...

Discrete Llama
Happy New Year, everyone!Some audiophiles have really gotten into preamps that use discrete opamp—basically using and bunch of individual transistors that make up the internal circuit in an IC. This...

Friedman Golden Pearl
Here's a good sounding lower gain overdrive from Friedman. Several options with this circuit with clipping and tone options on toggle switches. Fairly transparent, as they say.

Spaceman Titan II
Happy Fuzz Friday! Here's the Spaceman Effects Titan II fuzz, traced by Dino (Digi2T). I simplified the polarity protection, removing the BS250 in place of a simpler 1N5817 diode. Transistors need to...

OKKO Dominator
Here's a big one, and just so happens to be the 700th layout on the blog 😎—the OKKO Dominator distortion. It's a couple of JFETs pushing an opamp with active EQ, with a charge pump. Originals use a...
