Snagged a fully working Yamaha PSS-570 from the trash today, I forgot how good these things sound. This might be the one that I finally use the old Highly Liquid UMRK that I've been sitting on for like 8 years in, it deserves MIDI.
I've been waiting for one to turn up ever since I was roommates with a friend who has one back in 2011 (he still has it and uses it), but I'd pretty much given up, especially when eBay prices started breaking $200 a few years back.
EDIT: I forgot this is the one that can make some of the most iconic banda and norteño tuba sounds, too.
