I found a BT2 here on TB, and it's a bit bigger than my BML tuners, and the plating isn't quite a match, something I didn't know as I got the D Tuner before the BMLs arrived. Someone out there has the opposite problem. If your D Tuner is a bit bluer with a smaller knob, let's trade.
This picture is a good representation of the difference in color. http://flic.kr/p/e379bL
