yeah, the commercially available mod is like $50 or $100, but i'm not sure
if it's still available, even. from what i've heard, that does use a
double-click on the start/stop button to activate the reverse, and it's a
sealed unit that plugs in between the connector and circuit board where it
senses the double-click, and has a wire that goes to, apparently, pin #8.

i thought about a logic/timer circuit, to do the double-click thing, and
re-doing the strobe lights in 2-color LEDs, but for my purposes, i'll be
happy just to have a switch that doesn't look like crap.... my turntables
have had the crap beaten out of them long before i ever saw them (of
course, i have them working better than new), but the aesthetics of the
turntables really don't concern me, at this point.

if you come up with a circuit that does the double-click thing, let us
know!
