Seems like Korg are clearing the warehouse again, the SQ-64 -sequencer (see our review below )is available on Reverb.com at a 40% discount - now priced at $199 (which we would say is a fairer price tbh) but it does represent chunk of change. The SQ-64 has some really great performative random, pattern tweaking and other features to help make variations from shorter riffs.

Sadly for us Brits and pretty much everywhere else, its a US only deal.
However, we're also reliably informed that EU countries will also see some level of discount due to currency fluctuations.
