Definitely the best of the 303 emulators. I've used the older TB-3, X0X, and TT-303, but this one features all the features and programming options of the original plus some nice modernization like internal soundcard via usb, delay (tape emulation or digital), and distortion (3 different distortion modes). CV/Gate/Trigger options are awesome for integration into a modular setup. Main drawback is the 1/8" cables are hard to find in a suitable length for a studio set up.
Me and a friend tested all 3 Models (TB-303 original, TB-03, Cyclon TT-303) with 1 pedal distortion. On their own they sound nearly the same, the original had a touch to it that warmthen up things (maybe old electronics drifting) but the TB-03 and the TT-303 sound quite the same. The real diffrence was made when hooked to a distortion!! The TB-303 was shining and pumping and it was spectacular, the other 2 sounded plasticy and hollow. I think the TB-03 and TT-303 as the TB-303 can all shine with the right distortion/delay , but one distortion may not fit everyone. Without FX the diffrence is too little to me to pay X times for such a legend. I'm ok with the boutique remake. Btw, before i got i never touched an original tb-303 so I never had a feel of "the original" which makes the tb-03 as original as it can get.
this thing sounds like a 303 that woke up on the wrong side of the bed this morning, crunchy and raw. super fun to program thanks to the 303 style sequencer function and Last and definitely not least, CV GATE OUTPUT, hook this to any modular setup and its like a acid bass video game controller. so much fun
