Comparison starts at 1min.
A comparison video for the Roland TB 303 and the Behringer TD3. I think it's fair to say at this price and how it sounds the Behringer TD3 is a great 303 clone.
For me the down side is having the original sequencer. It's a real pain though there is a software editor which helps.
There was no processing on the two 303s.
If you like this sort of thing, I do short music and gear vids on instagram.
