Preamp for acoustic (new 2008) with volume adjustment and tonalitée and a button to boost the voicing or flat. Instalation very easy seamless just a few tweaks that I made myself without difficulty, if not a luthier is the solution.
The result is surprising until I used a humbucking fishman neo-d that I liked but were not talking about the same thing, the sound is as good as a guitar preamp with console adjusted at the factory and I would say it is better for my taste.
I like the other two micro model of rose which is the Fishman Neo-D model and a Seymour Duncan and I have more of one of my guitars a b-band preamp, none rivals this new fishman preamp which is much higher. (to my taste!)
The price is also very correct ($ 169.00 Canadian) for the its quality.
I would do this choice because I am very satisfied with the result.
PS My guitar is shaped band and if you go to the website it indicates that the Fishman preamp is made for any kind of cash.
