So! After much deliberation, I've decided to let this PU go. It sounds great with the right setup, and it records much better than a piezo. For those who use a PA type setup, or play with an acoustic group and amplify with a PA, it's ideal. I have found that I just don't use it often enough to keep it. I made a different mount for the jack, it now lives behind the tailpiece, and attaches with velcro. I'll include some adhesive velcro, and it comes with the original box, with literature etc.
Unlike the promo photos, it seems to sound best when placed over the bass bar.
This one has seen very little use, I'll sell for $350 shipped.
Here it is for $500 new
