Yeah, the OP-1 I think will heavily benefit from this! With the crunchy, somewhat flat OP-1 digital sound, the Heat could probably do miracles.
I impulsively almost ordered one today, after watching that Sonic State video! There are a couple of examples that I’ve heard, both here, and on soundcloud, where medium flat source recordings have been enrichened, defined, gotten that face lift needed to take it to new levels.
The destructive stuff is cool too, but for me, all the subtle and rich flavours before the heavy distortion starts to kick in, is what is really catching my ears.
I ended up not ordering. I don’t have the slightest clue if I can afford it or not for the time being. I must sort out some heavy bills this week.
