Age got nothin' to do with it Shboom.
Last year I took my Motif ES8 on stage and instead of taking one of the "+" polarity pedals I grabbed one of the pedals that I was using with my Korg KBs. Plugged it in and then discovered that the polarity on my pedal was a "-". Right in the middle of the song too! Since the MO can't switch PD polarity I unplugged the pedal before the next song started and of coarse the sound stayed on. I had to kil the power in the middle of another song and thankfully the sustain got reset. usually it has to reset when you just unplug the pedal but I guess "luck" was on my side that day....
