Muff's Modules & More

Has anyone ever modded a guitar pedal so that you could control certain parameters with control voltages?

For example, one major advantage you get with digital effects is time syncing. Software phasers can have their sweeps time synced and manually controlled (the Ableton Live phase shifter).

I would like to be able to manually twist the phase position in a phaser or flanger using knobs that output control voltages, or use LFO's with weird shapes that phaser pedals don't have.

Anyone have experience with this?

this is a good place to start.
Schematic is supplied so you can build your own, its a simple circuit.

ARDUINO ALL THE WAY! this is a maxon ad-999 with added cv

i just posted this in the eurorack forum.. i have a full technical explanation video to be uploaded shortly.

if you go to the videos page http://vimeo.com/21749580 you will find links for the information needed to do this.

but like i said.. i have a video coming sooooooon

Hyped about the tech video sir!

I'm super interested in this. I have been playing around with adding vactrols to guitar pedals and controlling them with a moog cp-251, but I would like to hear more about your arduino method.

Thanks for schematics doctorvague, these ill definitely help the with the vactrol
experiments. Then on to digital .....

It'd be cool if the manufacturers of guitar pedals formed an open-cv alliance and basically started building extra jacks into their designs with cv controls allowing all these petals to act as limited modular systems.

I think Malekko will customize their pedals for you to add CV inputs if you ask/pay.
