I bought this to fit a Bigsby B7 on to a Gibson Les Paul Studio Deluxe.
The instructions are straight forward and easy to follow. The pack includes the aluminium dog-bone shaped piece for attaching to the inserts on your guitar once you've removed the existing stop tail piece and bolts (an easy job) and a D-shaped piece that fixes to the heel of the guitar using your existing strap button and screw to secure it in place.
The metal parts have foam cushions to protect against scratching the guitar. There are imperial and metric screws supplied so you can fit it to either a Gibson or Epiphone Les Paul. Once the Vibramate is in place, use the screws supplied to fix the Bigsby to the Vibramate.
Once it's in place, you can hardly notice it and best of all, it's completely reversible in case you change your mind or want to put the guitar back to its stock configuration for selling it.
Please note, however, the the Vibramate V7 only works with the USA-made Bigsby B7. It doesn't fit the licensed version (the B70) that is made overseas.
