SOUNDS

Then there is the Hallu!
there is a sound very quickly by playing both bass and treble knobs
not a breath and no sound .. a SON! very warm (more than I Fodera)
The bass is really transformed!

OVERALL OPINION

I have since bought on eBay qq days.
What I like is the sound of course. Hot, defined now. If you push the treble bottom is marcus: D .. With a good compressor as BSE is the best!
I also like bcp warmth and presence with my passive fretless. All adapted to the wood. If I compare to Fodera (which also sounds very strong) it is more neutral than the Sadowsky. With these high-end preamp (Sadosky and Fodera), I finally found the solution for my sounds even if I change low for violin better. I do not regret this purchase an instant magic!
