While I love how they look, there really are much better choices for a trem to fit on in place of a stop tail these days. The Les Trem, Stetsbar, etc. They also won't have the problems that a bigsby usually does with fitting and tuning stability.
not a big fan of the product - but a fan of the man himself - get the book on his life - a great read -- but I feel trems have come on a bit since the "Blogsby" came about !!
