1 Powertronman 3 months ago Hi, this is a Towner hold down system to convert your Broadkaster to use a B-6 that’s completely reversible. No new holes will need to be drilled. It works great, just make sure your guitar player who is flying in to do gigs for you wants a Bigsby. (Mine prefers a hard tail) Everything is ready to go including the metric studs you will need for a Gretsch. If you want to install this on a Gibson 335 you can use your existing studs. Online price new is $273. My price Papal gift is $185 plus $10 shipping. This includes the Bigsby with standard flat handle!
