Couldn’t really find a good description of this pedal other then it’s a Fuzz-Wah produced in the 70’s by Jen. Here’s my take based on the schematic. Just like many of the other fuzz wahs I’ve seen and working on layouts for this is essentially a classic inductor wah with a fuzzface type fuzz. There’s … Read more
Hadn’t done a wah in a while and thought I’d do project where you can build several old school wah circuits on the same board. Many of the early wahs back in the late 60s were based on the original Thomas Organ CryBaby, and as a result many of them follow the same topology with … Read more
The Colorsound Fuzz-Wah, or to be exact the Colorsound Wow-Fuzz! A new version of a funk-tastic old timer. The original 1970’s two transistor silicon distortion stage delivers the fuzz and the classic inductor based Colorsound wah circuit gives you the wow! Ah, the inductor based circuit you say. Been awhile since Colorsound did that, right? … Read more
Saw this one over on the Tagboard blog and thought I’d give it a go for Fuzz Friday. It’s a silicon variation of the Maestro FZ-1. Originals use a single AA battery (1.5v), so I’ve included 2 voltage diving resistors to drop the the normal 9v supply down to 1.5v. (The yellow trace in the … Read more
Not much info on this one, but basically it was a compressor made by Univox in the 70’s as part of their “foot” series. Seems to be loved by many and was recently requested. In addition to the schematic posted in the request section I found another schematic posted over at FSB, so I made … Read more
“The Hi Volt is a mid- to high-gain dirt box, with a fully saturated effect that is internally charge-pumped to 16VDC, and brandishes a high headroom, custom-tuned 3-band active EQ. This high-voltage configuration allows for very flexible and potent sonic possibilities, ranging from blues to metal and everything in between. With its generous low-end wallop, … Read more
Another tube booster/overdrive created by frequency central over at FSB, schematic. What does it do? Well it does clean boost with the Gain set at minimum, flick on the Dirt switch and you get some nice diode clipping too. Turn up the Gain and you’e into overdrive territory with diode clipping, flick the Dirt switch … Read more
Another submini tube based booster/overdrive pedal created by himister over at FSB, schematic. Make sure you are rated at least 25V due to the increased voltage from the rectifier. An additional mod you can do is replace the trimmer with a 250k pot so you can control the distortion produced by the tube on the … Read more
Original FSB thread and schematic available here. Rotary Switch is 2P5T and they are not always numbered. I’ve called the 2 poles A & C. When the switch is on “A-1” position on the other side is on “C-1” position… and so on. Original circuits’ schematics use Ge diodes but the Apocalypse’s one doesn’t. Need … Read more
Got a request for this one. It’s a effects loop buffer that’s a solid-state version of the Dumbleator effects loop buffer. It’s equipped with an internal charge pump that converts a +9v supply to +33v. Very useful for keeping your effects loop free from signal-loss. Since it runs at a much higher voltage than most effects, make … Read more
