A very nice way to try a Bigsby on a ES-335 - though it didn´t fit my 2008 Gibson ES-335 Custom Shop perfectly (3,5/5). The bigger metal part was a bit too long. Also it´s hard to get it following the body shape.
After I knew I really wanted a Bigsby I only used the smaller metal part on the side of the guitar and the "Custom Made" sticker. I drilled two holes on the top of the guitar, direct mounted the Bigsby and used the "Custom Made" sticker to cover the stop tail piece holes.
