It sounds just like a 303 (I have had both), has a retune botton, for when the tuning drifts. Is midi compatible, has bigger knobs, the filter has more range and woomf. And costs about 90 quid second hand.
Also, the wave type is constantly variable between square and sine.
Shit. I saw one of these on ebay for about £50, but didn't bother bidding as I thought anything that cheap would have to be a bit shit.

What's the filter like for routing other audio through? I seem to remember reading this was possible with the unit and a 303 emulator plus a decent analogue filter for under £100 would be very nice indeed...
