A vintage big box The Worm with some useful improvemnts and mods by Madbean. The power section have been reworked by a voltage doubler and a voltage regulator for 9v to 15v operation. An internal volume trimpot is added. And the unknown original vactrols is replaced by a trio of LDR/LED pair. Schematic and more … Read more
Schematic is avaiable HERE. I added a 100ohm protection resistor across the trimpot and the lamp driver transistor (Q1).
Here is a layout for the DOD FX22 Vibro Thang (Vibrato / Phasor) 04/05 Layout Updated: LM358 pin 4 and the 18K resistor from the bottom LM13600 pin 9 were connected to V+ instead of ground.
Here is a layout for John Hollis Easy Vibe. I’ve added Mark Hammer’s anti-ticking mod and Piotr Zapart’s LFO mods. Try 5K/20M LDRs.
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:
This is Madbean’s version of the famous Univibe pedal. I’ve added a “Multi-Vibe Mod” to it. You can find all infos on this circuit or buy one of his PCBs here: http://www.madbeanpedals.com/projects/index.html 09/11/2016 Layout Updated! Changed the charge pump daughter board. There’s also a different but verified layout by Savvas in the Forum section.
Request for this nice sounding chorus/vibe pedal. Thanks to Scruffie for his schematic. It will fit in a 1590B if you want the aggravation, but a 125B would probably be a better choice. The effect needs a 15V supply so you can either use a standalone 15V adapter if you have one, or build the … Read more
