Bought this mainly to use it on vocal but found it also to be very nice on direct input bass.
The tube knob will get you from totally clean to quite distorted yet sounding soft and harmonic, and has quickly become a favourite.
Giving the vocal a little bit of compression pre-recording can also give you an easier startingpoint when you start working on the track in the DAW.
The possibility to route the eq before the compressor increases the functionality further, and is really useful when recording for ex. a bass.
The knobs could have had clearer markings.
The thing I miss the most is a power button on the front panel, instead of one switch on the back and yet another on the cable.
I definitely recommend this unit to others.
