I'm so sad to see this go, but I'm moving and this is too big and heavy to take along with me.

This is a fairly rare, legendary synth.

The Ensoniq SQ80 marries an analog filter with gritty 80s digital waveforms that include an endless selection of various oscillators as well as various attack sounds.  Patching capabilities are many and flexible.  Features polyphonic aftertouch for amazingly expressive playing.

Plays like a charm.

Pedal is a Casio.  Works fine.

Original floppy disk with patches.

Cartridge doubles storage capacity patch storage as well. 

Flight case is solid.  The foam padding inside the flight case is like anything made of foam rubber that is nearly 40 years old -- it's deteriorating -- but that's something that's super easy to replace.
