Heres the deal, I have only been on the market since 2011 and before that, technically, you would install a BIGSBY B7 because it has a down tension bar and you would have to drill the body with extra holes and have two empty holes left in the guitar body. Fortunately, BIGBSY makes theBIGSBY B3 which is the same as the BIGSBY B7 without the down tension bar… So, that is how I figured out how to design the down tension bar to take the place of the BIGSBY B7. Relieving you from having to drill ANY extra holes in the guitar body.
So here is what you can do, buy this package and replace the stop tailpiece studs for about $5.00, you’ll see why and what to do at these two links and you’ll be ready to rock!
