Transparent sound very good for voice and instruments
I like the preamp starts to 20db (an attenuator default) and the possibility of EQ settings, which Shifts to intervene on his finesse.
Simplicity / Effacité (key words)

OVERALL OPINION

Very good quality / price ratio
I own two and I search to make me a 6 rack 8 preamp / EQ.
