I gotta couple cool things on sale right now...I need the money so hopefully someone will be interested!
This is a cool little device you plug on your guitar (or FX pedal) that gives you a really cool, choppy tremolo-like sound...but it's a bit more percussive than that, as the name suggests. Made in the sixties I think, and famously used by SPacemen 3 on classic songs such as How Does It Feel? (http://www.youtube.com/watch?v=e_WuHri_DFk&feature=player_embedded)
Sure, you can find clones...from time to time, if you're lucky. But an original is very rare and harder to find.
ACE TONE FR1 RHYTHM ACE ANALOG DRUM MACHINE
One of the best analog drum machines ever! Made in the late 60s...sounds EXACTLY like the one Martin rev used on the first Suicide album.
UNFORTUNATELY mine isn't working, but if you know someone who can fix it, you might grab a bargain and have a very rare and valuable piece of vintage gear in your hands.
