Your #1 Bigsby Retrofit System by TOWNER includes:
BIGSBY B6
TOWNER Down Tension Bar
TOWNER Hinge Plate Adaptor
One 2" Strap Button Screw
Four Hinge Plate Rivets (*I will install the rivets for you.)
Four Felt Pads
*If you do not have a Gibson guitar get the METRIC studs.
And I recommend the 1 inch spring for 335 style guitars because the Bigsby arm, over the archtop, sets the arm too close to the body.
BIGSBY® B6 Kit with TOWNER System
The TOWNER Down Tension Bar manages your sustain controlling your break angle.
The TOWNER Down Tension Bar allows you to control how much string tension you want.
Recommended to set the Down Tension Bar just below the saddles of the bridge.
The TOWNER Hinge Plate Adaptor is designed to provide a flat surface for your strap lock or strap button on the BIGSBY® EX-SHORT hinge plate.
The TOWNER Hinge Plate Adaptor slot provides room for exact placement of the BIGSBY®.
The TOWNER Hinge Plate Adaptor and 2″ strap button screw acts as a retainer holding the BIGSBY® to the guitar body, relieving you from having to drill four extra screws into your guitar.
I recommend the 1" inch Spring for B6’s, provides a comfortable distance between the guitar and the Bigsby arm.
‘Some’ ES-347’s have the studs set lower on the guitar body. If so, use the TOWNER B3 KIT because the studs are set further back on the guitar.

First off, Towner Customer Service was great. They answered all my questions and help pick out the right kit, and the parts guide was also helpful. The B6 kits works flawlessy. I had mine installed by a professional, along with a Gyker Roller Bridge and I couldn't be happier.
thank you for the fine review Nathan, greatly appreciated. You should checkout the string through bar from Callaham guitar parts
