Well built, everything is solid, no wobbly knobs for me.
Super small form factor for a 3-way mixer, fat filter and vca.
The downside is that especially the mixer knobs are hard to control, they're very close together with the inputs right above them. This makes them less ideal to 'play' with. The other knobs are accessible enough.
High boost with a bit of resonance (Especially when fed with the RitS BOC) gives immensely fat bass sounds. Great module!
