"This is the nicest Korg Poly-61 you can get. Here's why:
Fully restored and upgraded this fall by Perfect Circuit Audio, where they replaced the caps, modified the battery to a removable slot to prevent the dreaded Korg battery board death, and installed the Tubbutec ModyPoly modificiation, which adds a power arpeggiator mode, midi control of arpeggiator click, midi control of filter, pitch bend, midi output for chord mode, new LFOs, and much more not available on the original Poly-61M Custom gray walnut wood ends by Allen Coppock of SynthSpa — he's the only one who offers custom ends for the 61m and there as a 4 month wait on these.
The Tubbutec mods add:
Midi in + Midi out (better and more durable than the original 61M midi ports)
Sustain Pedal input
Additional play modes: 2 Voice, 3 Voice, Polychord, extended unison mode
New arpeggiator / sequencer mode: Powerarp
All functions are easily accessible via buttons: suitable for live use
Midi controls arpeggiator clock, triggers the arp, filter, pitch bend * and more
Midi output of arpeggiator, chords and powerarp sequences or simple keypresses
S/H LFO and fast triangular LFO for filter
Midi channels and various other options can be configured without external tools
Very easy to install, no soldering required (a bit of soldering if you want midi controlled filter and pitch bend)
High quality midi sockets and sustain pedal jack
Condition:
The wood sides are brand new
The internals are fully refurbished and functional
All buttons, keys, and LCDs work perfectly
The surface front panel and key tray has a few scratches and scuffs (see photos) but is overall in Very Good condition. There are no dents in the metal. I have provided high resolution photos to show the condition accuracy"
