OK so the OB-Xa is fatter than the new OB 6?
I had Prophet 6 and OB6 AND a Prophet 5 rev3 and OBXa. When it came time to weed out all the analog poly's to make room for some new things, you can guess which ones were sold.
Granted, I think the DSI stuff is great and I would own them again in a minute if I had the room and need, but indeed the oldies have a glorious sound. I have no idea what it is, but I could never get close to the sound of either from the new guys..not that I sat around trying to do so.
I'll also add, that for my purposes, tuning is not an issue. Just hit the tune button at the beginning of a session and everything is great. Can't imagine having one of these on the road, though. But obviously guys did it for decades.
I would like to get a Prophet 12 again, though. I miss that character section before the filter. Nothing I have can quite get that pre-filter grunge.
I just finished building the Deckard's Dream, and it has that timeless sound to it, IMHO. Very musical sound to it. I will undoubtably jump on the new project, both because I'm impressed by his designs and I really enjoyed the build process.
