Here’s a weird chorus from Valve Wizard based around a PT2399. In Merlin’s own words… Chorus is created by passing the signal through a very short delay line, somewhere between about 8ms and 25ms. The delay time is modulated and the delayed signal is mixed back with the original un-delayed signal. Some feedback (‘repeats’) is … Read more
Here’s the Pitch Pirate with board mounted pots. Like the Deluxe version, the LFO is designed to be grounded when the effect is turned on (hence the pad at the top of the board). Just use the true-bypass wiring diagram in the General Layout Notes and leave out the LED wiring. Then just connect the … Read more
Got a request for this one. This was originally designed by John Hollis and has since been modified by various folks in the DIY community. Like the latest version of the Little Angel chorus, it has a switch to do either vibrato or chorus tones. And the Mode switch allows for different speeds (Leslie, Normal, … Read more
Had a request for this one and ended up drawing it up in Eagle. Rick Holt (frequencycentral) over on DIYSB designed this chorus and this is the latest version. It differs from earlier version with 2 toggle switches: One changes the effect from chorus to more of a vibe, and the other changes the sound … Read more
Here is Brian’s new PT2399-based chorus. You can find all infos from his website here. Here is a video by Ciaran:
Madbean’s great new project based on Earthquaker Devices Sea Machine. Original infos available here. 17/07/2016 Layout updated! Changed 33n cap to 3n3 and 10k resistor from PT2399’s pin 14 back to 1K.
Here’s a simple, fairly low parts count chorus based around a PT2399, designed by Rick Holt (aka Frequency Central) from the DIYStompboxes forum. I’ve drawn 2 versions, one with board-mounted pots, and one off-board pots. The 2nd IC (NE5532 in the layout) can be any dual op-amp (a TL072 works well), just socket and experiment. … Read more
This was a request from my friend Cody from They Remained Silent blog. The Pitch Pirate is a vibrato/chorus pedal, and the deluxe version adds a PT2399 based delay. It also has the ability to modulate over an octave as well as control the waveform of the modulator, giving you a huge range of tonal … Read more
Stumbled across this effect while looking for a completely different schematic. It’s a low cost chorus designed by Merlin Blencowe (here’s his schematic for reference), using a PT2399. It generates deep modulation and a very thick warble (here’s a sound clip).
And I may as well add this one as a separate layout so we know what versions the comments are based on. This changes a cap value and adds an Effect Level pot to the CE-2. If you want to add an Effect Level pot to the guitar CE-2, just use this layout and swap … Read more
