I'd miss some things, but I could play out the rest of my career as long as I have something to play bass lines with, a drum machine (or drummer), and something to pound out chords on ... preferably an electric piano type sound. To be honest - my Antique Korg i5S that Boo sold me, would do the trick nicely ... IF it had to. My PA900 is filling the bill quite well for the next little while and there is nothing on the horizon that excites me. NOTHING.
