transistor preamp
3-band equalizer
3 position selector: boost treble, bass boost, neutral (almost passive)

UTILIZATION

manual very clear, the configuration application on the net. The designer corrects him even possible errurs your design and submit your opinion by mail.
After validation, very fast delivery.
Warning: packages subject to customs duties: for me: value $ 240, or 180 €, 60 € through customs, leaving a total price reasonable given the quality of the product
the resulting sound, after the initial setup is excellent, very versatiles.Il settings well enough to adjust the output level of the module and severe acute before closing the plate.
Little advice: make a aouverture back bass and insert a battery compartment with hatch (10 € on the net)

SOUNDS

you can do everything, sutout with 3-band EQ
slap the most nervous at the fat and "roots" for reggae
with the selector can choose to boost the bass or treble, I personally found the boost acute useless. By boosting the bass, you can have a range of sound with the equalizer.
I installed it on a passive Godin SD5, because I could not afford to buy a Fender 5 string active type, and there ........
I have a new bass! keeping qualities of the superb violin Godin!

OVERALL OPINION

used for a year, without fail. Very economical batteries.
Value for money impeccable
Very nice communication with the designer
DVISER strongly to those who want to move from passive to active without separating from his favorite instrument!
