This Ebony active back will be tuned around 214 Hz, and will add a touch of complexity to the tone of the guitar, on the midrange, leaving the soundboard monopole very dynamic, sensitive and projecting. 🙂
I have to say, I have the feeling I am talking to myself. Is there anybody out there interested in acoustic guitar design?  .. |
I'm definitely interested (currently reading your book). I've been curious about the function of the active back. Is the idea to keep its mobility high enough to color the sound, but not so active that it sucks too much energy from the top? How do you arrive at that sweet spot?
