Collin's Lab: Guitar pedal hacking with Arduino

Instead of chaining multiple guitar effects in search of a new sound, I decided to mod just one. Using an Arduino microcontroller board + digi-pot chip, I was able to add a variable gating effect to a fuzz pedal.

The 3 best makers all have alliterated names - Collin Cunningham, Kip Kedersha, and Derek Diedrecson!

that was really cool!. however, for the sake of argument--couldn't you have just accomplished the same thing much more simply by putting a tremolo in front of the big muff? one like the Tremulus Lune (there are several others) with multiple wave shapes. The double wide/stereo tremulus lune would give you even more control over the wave shaping

@AresExodus Youmay want to take kip from that list... he doesn't make anymore D:

[Muscleduck]

The effect with square wave reminds me of Guerrilla Radio by RATM :)

squire sounds like 60-80 rock

sawthout sounds reversed

sins sounds little bit wavy

@monkeyxx you do realize that these are DIY projects for people who like to tinker with electronics.. sure u can buy pre made guitar effects pedals but its more fun for these guys to built their own.

@monkeyxx Everything he makes could most likely be done a simpler way, but that's not the point. People like him do stuff like this to

1. Learn new things and improve skills, and

2. For fun!

what the difference between reversed saw and ramp?

DUBSTEP !!

i dig this video and arduino, but the actual sound means nothing without good songs or a unique playing style. I have my pedals, guitars and amps but manage to turn any guitar, any pedal and any amp into my own "sound" any day by how I play it.

[2PlayGuitarNow]

you're so right about finding your own sound. buying tons of pedals won't do the job.

[raindogred]

you can definitely achieve the same result without hacking your big muff. just run a modified version of colins sketch to control an LED on a breadboard, hook up a 2 jacks on the other side of the board and an LDR then turn out the lights. U get the same sound to my ears - why you would want that sound is a question you have to ask yourself :0)
