"Anyway, I was a geeky kid who couldn't afford most of the stuff but still managed to spend 3 hours there most Saturdays, much to the chagrin of the owners and salesmen. I played with some very odd things as they showed up... and one of the oddest was the Dynacord Rhythm Stick.
[Modelled here by Robin Horn] It's guitar shaped, with 8 "fret" buttons, and two pressure pads. The idea is to whack the pads with your thumb and fingers (sort of in a "slap bass" motion) and whatever buttons your holding down will "trigger".
"Actually it was completely retarded - you can see how limiting it would be for making music... One of the best things about percussion is that you get to use all 4 limbs to make sounds - this reduces you to one actual sound-making limb. But like a stand-up simmons drum kit, this could be sort of a fun thing if you were an 80's sequencing band.
"So today, it showed up on Ebay. I'm considering doing a $50 bid just to see if I get it. But I'm afraid I'd win it and have this ridiculous instrument."
