“A down tension bar providing VST,
Variable Strings Tensions”
Back in 2007 I invested in a Gibson ES-335 without aBigsby vibrato bar factory installed. The guitar was a good deal and at the time and I didn’t think I would really need or want a Bigsby vibrato bar. Well, it turns out I did want a Bigsby vibrato bar the more I played. I began speaking with guitar technicians and the suggestion of putting the Bigsby B3 on instead of the Bigsby B7, to prevent drilling extra holes in the body of the guitar, came up often. I installed a Bigsby B3 vibrato bar. After I installed the Bigsby B3 vibrato bar and began to playing the guitar, the strings would slip off the bridge because there wasn’t enough down tension between the bridge and the vibrato bar. So, I began to think about how I could prevent the strings from slipping off the guitar bridge. I came up with a number of ideas to remedy the issue of strings slipping off the guitar bridge by making use of the existing studs mounted in the guitar. Settling on the design you see at this website, it ended up providing more than one benefit to installing the Towner USA vibrato retrofit kit.
- The Towner kit mounts in place of of the stop tailpiece on existing studs.
- The Towner kit rests over the strings, applying the necessary down tension needed per the height adjustment of the studs.
- The Towner kit can be canted by adjusting the height of each stud [VST]. Canting the Towner kit provides even down tension over the strings.
- This kit can be adjusted to whatever height you want and or need to accommodate the action of your strings and bridge height.
- The Towner kit alleviates the guitar owner from drilling holes in the body of the guitar, when installing a Bigsby B3, B11, B30 or B6o vibrato bar.
