Considering the price, there's not much negative to say about this synth. The build quality feels good, nice and sturdy.
The sound is full and fat, capable of making both deep bass lines and screaming leads.
Modulation is a lot of fun, and the patchbay options open a whole new spectrum of sonic capabilities.
One downside would be the number of "hidden" features that you have to remember by head, as the shift combinations aren't printed on the original overlay.
Biggest downside for me however is the filter, it gets way too dirty and muddy when you crank up the resonance imho.
Nonetheless, definitely recommended!
