Simple Clipper Distortion
I found this layout going through an old folder on my computer. Pretty simple IC-based dirt circuit and will fit in 1590a. Here’s a sound sample.
EHX Big Muff – Triangle
I know, this is the 3rd different BMP layout I’ve done, but this is the one I’m the most happy with. It will easily fit in a 1590B, it has board mounted pots, and said pots aren’t all in one row across the top. As with the other Big Muff layouts, you can build pretty … Read more
BearFoot FX BlueBerry Bass Overdrive
Here’s a great bass drive from BearFoot FX in Sweden. Kind of similar to a RAT, but not really. It’s a completely different beast. Q1 calls for a 2N5952, but other JFETs should work there too, just socket and mind the pinout.
Kay T-1 Tremolo
Here’s a 1590A candidate. The Kay T-1 Tremolo originally came in a plastic housing with a treadle that controlled the speed. Apparently similar to the Vox Repeat Percussion tremolo, but a little smoother.
Maestro FZ-1S Super Fuzz-Tone
The Maestro Super Fuzz-Tone was introduced in the early 70s. It uses 6 transistors, 2 of which are used as clipping diodes. Original transistors were 2N5133s, but 2N5088s or BC109Cs can be good subs. I’ve built 2 clones of this pedal in the past (though not with this layout) and used 2N5088s with good results. … Read more
Maestro FZ-1B Fuzztone (2 transistor version)
This was (I believe) the 3rd iteration of Maestro’s Fuzztone fuzz pedal. The first 2 used germanium transistors and AA batteries. This marked the changed to silicon transistors and a 9v battery. Originals had 2N3860 transistors, but 2N2222s or 2N3904s would probably work just fine. Couldn’t find any info on the diode, so socket and … Read more
ESR Graphic Fuzz
Gnarly, oscillating fuzz tone–this is a bit of a weird one. The original used both positive and negative 9v (which I have a hard time wrapping my head around). FSB forum member Induction altered the circuit to support standard power supplies, so no need for a 9v battery or adding a +/- converter. And it … Read more
Simple FET Blender
Here’s a simple blending circuit that uses a JFET to allow you to blend between effected signal and clean signal. I’ve used this on Big Muffs before and it’s quite useful.
Fulltone OCD – Version 1
There are now 4 version of the OCD. The latest has a few guitarist I know wondering what was wrong with the last version, so if you’re looking to go back to the original circuit, this layout is for you. The OCD one of the most respected overdrives out there. Derived from the Voodoo Drive, … Read more
Lovepedal Purple Plexi 800
Here’s another Lovepedal circuit. It’s similar to the Black Magic, adding a frequency control, and is supposed to sound like a Marshall amp.
