Anyone using a Schertler DYN-G with their acoustic guitar? I've heard it used on a Mandolin and was astonished. But what few user reviews by guitarists I've been able to find have not been that enthusiastic. I won't go into the many acoustic transducer systems I've used in the past 15 years - -suffice to say that I've never been all that happy with any of them. In my experience, the ones that sound "natural" are very prone to feedback; the ones that are feedback resistant don't sound very natural to my ear. I heard the Mandolin version of the DYN used at decent volume at an outdoor show, with no feedback or low-end "whumping". I'm not sure how it would behave with the larger, more flexible soundboard of an acoustic guitar.
