UTILIZATION

The configuration is simple and rather intuitive.Les various connection capabilities are enormous.
The independently made to parameterize the lamp and transistor provides a real plus.
Outputs Low, High and Full can either have the bass or treble, or both (full). This is useful if you work with several speakers.
Contour settings and equalization complement. It can push its settings without any problems and refine them.
The compressor and chorus are a little small hurt but work. However, I prefer to use other machines specially dedicated.
This preamp is a sort of Swiss Army knife bassist I find everything in there.

SOUNDS

The factory settings allow a wide range of sounds. Funk metal through the rock, it is very versatile.

I use it mostly with a low active Ibanez BTB 400 accorée to play in the metal, I'm very happy.

The only problem is the saturation lamps. When did Full selects the preamp breath but it's long since I 'lai not been checked.

OVERALL OPINION

I've had two years I used to rock and metal, it is very suitable. It is suitable for other styles too, it was used by Victor Wooten and Les Claypool among others.

I love its flexibility and huge possibilities. Management lamp / transistor is excellent, everything can be set on the preamp.
The value for money is great, with the experience I remake this choice without hesitation.

A preamp very complete!
