I have just recently bought a new A201
It is a beautiful guitar with a great sound. I am impressed with the BBand dual pickup systems either A2 or A2.2. They require a minimum of alteration to the guitar. A 12mm hole for the jack plug / strap button and a 3mm hole drilled for the under saddle transducer through the bridge.
I notice from other posts that there is probably a rosewood shim at the bottom of the saddle slot. BBand say there is no need to remove this as the UST is only 0.4 mm thick.
I imagine it is a case of try it and see what happens? The action will be better without the shim but as the UST is considerably thinner than the Fishman, I could run into fret buzzing
Anyone got experience with BBand on Avalon guitars or any advice on this?
