Hing Hon ek-001 keyboard modified by POTAR

This would be a great addition to a studio for making weirdo soundscapes, crazy pitch-bent bleeps, and other fuzzy madness.

Modified DOD FX70 Stereo Flanger

From added LFO tones and noise to delay-like repeats The mods are pretty simple, you replace the 3 internal trim pots with comparable-value … Read more

July 13, 2023February 24, 2012 by POTAR

I bent this Yamaha MU-5 a few months back and never posted the pics here. The ic is surface mount and has tiny legs that make it a chore to solder to, but the results are worth all the solder stress. I love to chain this thing to my Roland Tr-505 or Alesis HR-16 and … Read more
