After wanting an OP-1 for years I finally got ahold of an OP-1 used for a decent price.
It’s an absolutely amazing device but I probably wouldn’t suggest it so someone as a first synth purchase.
Prior to buying it I got a Novation Circuit and then a Digitakt.
The Circuit is a far less expensive device (can be had for 200-300) and is very flexible.
It fits into a similar realm as an OP-1 (jambox)
