"This thing is great for dreamy evolving pads, drunk sounding horns, lofi surfing, and 80’s car chases.

The filter is modded to allow free playable control over cutoff and resonance, with a 2 pole/ 4 pole switch installed for more variety.
The chorus has been modded to allow adjustment of the rate, going into audio range for ringmod-like effects, adjustment of depth, and a true mix knob allowing for control between fully dry and fully wet.

There’s an external input, so you can run some audio signals in and override the noise (ext input level follows noise/filter envelope).

The internal battery has been replaced with a battery clip for no-solder battery swaps and a brand new battery has been installed.

All the tact switches have been replaced, so no annoying switch bounces while trying to program a sound.

The instrument is painted to match the green lettering in the programmer menu."
