ACID
Spiros Lazarides, 06.11.2019
I use TB-03 to my home studio
it sounds definetly different from tb-3
the sound is come very close to tb-303
i love the idea of fx distortion and delay
it is portable works with 4 batteries also
has a small speaker but you can also listen from the headphones so it is good idea to get also a bag
the sound and the construction quality is good.
dont forget to buy also a mono mini jack cable for your mixer!!

Sounds good, works like a charm
JP Formosa, 19.06.2019
Sounds like it should, although I have no other source to compare it to, it just sounds good. YOu will spend countless hours making acid and simply having a blast with this machine and at the price its a no-brainer. The on-board effects and midi implementation are also welcome.

I don't like the micro USB power and would have preferred a DC adapter in order to reduce humming but this also means that the device can be powered using a power bank which makes it very portable.

The build quality of the device is also great however I am a bit weary about the knobs which are a bit small and have some play however they are not too bad. Considering the price this is an excellent piece of kit.
