I am a big fan of Bigsby vibratos, but I have to admit the Bigsby's can't hold a candle to the Duesenberg tremolo on my Starplayer TV Fullerton. I have a few Gibson guitars (Gibson Custom Shop ES-335 Dot and a 1971 LP Custom) that I always wanted to modify for a Bigsby, but once I saw the Duesenberg Les Trem II, I decided to try it out. I purchased the nickel Duesenberg Les Trem II and installed it on my 335. Easy as pie! If you can change strings on your guitar, you can install this trem. It works great. Guitar stays perfectly in tune. And no mods required. I doubt if I will, but if I ever want to go back to the original stop tailpiece, I can do it in a matter of minutes. Great product. I'll be picking up a gold one for my Custom in the near future!
