It's a circuit bent Yamaha RX-17 from the mid-80's (Quality sounds, but they still have that retro vibe). It has a 25 point modular patch bay, that when you connect the points with alligator clips, create modulations, voice swappings, pitch shifts, distortion, and other effects. It has around 600 effect combinations. It also has 6 3-way switch and 4 knobs to connect to the patch bay. It also has a memory bank of 99 patterns and 2 drum kits (Standard and Latin), and all kinds of other features I don't feel like mentioning. Made by Toronto artist and circuit bender, Matt Durant. I'll post some sound clips later, here's a pic:

looks like a lot of work. I have an alesis from the 80s. :/
...because the last thing the world needs is another metal guitarist.

Me.

My band.

I like Fall Out Boy. I don't like you.
