UTILIZATION

Super simple, effective, high-speed handling (for allergic types of jobs ...)

SOUND QUALITY

I find it really great ....
I use it with the microphone Behringer B2 Pro (aussi..), the result is surprising, especially for the price. (one as the other ...)
discouraged the use of the limiter which "food" really sound.
if not, I think it sounds good, be careful, be cool on pots (no need to put a background ...), otherwise BREATH.
I use it recently, but for now, I have better results with this little box with my Focusrite VoiceMaster home (it is true that I have recently also, and perhaps it is more difficult to use ..)
CLARIFY: this is a preamp, (not something to play better guitar players embittered ..), use it for what it is made.
it's a purchase that I recommend (for 59 euros has frankly-you one today)
OTHER PRECISION: This box uses a 12AX7 tube, please try other bulbs, in fact, each lamp has a different sound and it may well fall on a super light like a shit, the effectiveness of the box suffers ...

OVERALL OPINION

I recommend a purchase for the price, the result is there.
forget the clutch (especially when recording ...)
phase inverter parfoit very useful.
super convenient to use, use super simple, compact ...
I am planning to buy other (with rab lights to find the right with his killer ...)
