I bought one of these to replace a fishman that I was getting a low frequency buzz from. I had B Band fitted to a Collings D2H in 2008 and it's just a great well balanced sound.
Anyway I decide have a go and fit one myself and I am definitely not a do it yourself person. The preamp fitted into the hole at the back of the guitar with some adjustment to the nut inside the guitar body. B band provide a card board guide to help you get the placement right for the pick up (transducer is it called?) you know the flat thing that sticks to the bridge plate! In the end I decided not to use the guide.
Just remove the film to reveal the sticky bit then hold it in one hand with fingers at either end and stick it centrally onto the bridge plate feeling for the back edge of the plate. Dead easy, and that was it. Boy, did I feel proud.
The sound is well balanced, warm and loud. The volume control is also a neat touch. Really love the sound.
Recommend it, thanks B Band
