A characterful oscillator and filter for this price?
I got this as an extra synth 'voice' to go with my computer/modular and midi gear. I have an O.G. FAT FreeBass 383 from back in the day that I modded and it sounds like a monster. So I was delighted to see this make a comeback and it has to be the cutest little desktop synth ever! I also have a BassStation rack, BS2 keyboard, Cyclone TT303, DinSync 303 Euro module and a modded x0xb0x. So I kind of do like 'that' sound.

There are no bells and whistles - you get a nice 'Autotune' VCO, VCF, VCA, midi in and filter in. No its not a TB nor would I want it to be. It can get close to that kind of sound but I think it has a character of its own. As it is analogue, only midi note and accent are available to send to it so of course no automation. But here is the thing - it is more fun playing with the knobs and recording the audio performance! This little guy likes being tweaked and you will enjoy doing just that!

Its so straight forward and quick to use (once hooked up to a suitable sequencer) I often find myself reaching for it rather than the TT303/BassStation 2. You really do get a great sound for not a lot of money. I'll probably pick up another soon.

So cool/so cute!
Cons - Its not a TB303!
Pros - Its not a TB303! It can do that fairly convincingly but being able to set the mix of waveforms gives it a lovely character all of its own, its so small and portable it should be on every desktop and it really is hands-on. You have to tweak it live and when you do you find yourself enjoying tweaking it live!

Great little box
Mr Peculiar, 12.05.2017
Ive been chasing the sound of a 303 for a long time and this little beast just sounds great.
Overall the build is very tidy and does not take up much space and its sound is just what ive been looking for.
100 times better than any plugin youll buy.

A couple of the pots seem very slightly wobbly but nothing to worry about.

Highly recommended !
