"Hello synth-kids! Here’s an Alesis A6 Andromeda. I bought this from its original owner in 2009. Since then it has been a faithful companion in my professional studio, used on several TV gigs. But – it’s time to pare my rig down, which is good for you!

This unit has several fringe benefits:

It’s in good shape – see pics.
I have a 2048kb memory card installed, which adds another 8 banks and 1024 (!) patches, loaded up with sounds I’ve collected from the internet.
A Gator road case is included (it will ship in this, with additional protective packaging of course).
The original printed manual + foot pedal are included.
All voices / VCAs / filters tune properly, no dead voices etc. The results of all tuning, calibration diagnostics, and SRAM check are shown in the pics."
