The build quality is simply excellent. The knobs and switches feel sturdy and build to last. Everything works smoothly. The module is definitely pleasant to use and looks gorgeous.
Being a combination of VCA and low pass VCF, the Black LPG really shines when both are used together. The typical vactrol snappy sound is a real joy. The VCF used standalone provides a great sound too.
The drive switch brings another layer of character to the sound. From fat and buttery lows to screaming highs (with the resonance set fully clockwise) the Black LPG has it all.
The EG output is a welcome addition to the ins and outs of the module. It is very useful indeed to drive another sound somewhere else in the rack.
The Black LPG does not provide any CV input to drive the resonance. Though it would be a nice-to-have feature, considering the fact that the place on the front of the module is limited, I think that an EG output instead of a CV for the resonance was the right decision to make.
