Korg A3 Guitar Multi-Effects Processor with 3 Expansion cards

This is the legendary Korg A3 Effects Processor.
It has up to six simultaneous effects, and has an excellent interface to dial in any sounds you want.
It has a massive selection of effects including distortions, overdrives, tube-emulations, compressors, many different eq modules, speaker simulation, chorus, phaser, flanger, pitch shifters, numerous delays and reverbs.
It has 100 patch locations and a very good MIDI implementation.
I have also included three of the rare expansion cards that expand the effects and capabilities of the A3, plus an additional 100 presets per card. The cards are:
SPC-01 Guitar Card
SPC-02 Studio Card
SPC-04 Guitar Card II

This unit has been made famous by The Edge from U2 -"Mysterious Ways".
The included SPC-01 Guitar card includes many if the effects used by the Edge.

This unit is in very good working order - there is minor rack rash.
