26 duojet55 2 years ago Coldfire, the Floating Sound unit actually works well, sustain-wise, but it does take a little bit of the chutzpah from the over-all tone. I like it on the White Falcon because it's a part of the guitar. As for the padded back, it's real function was to hide the string mute's access plate. It was marketed as being a deluxe feature for player's comfort, but that is mainly sales BS. It would really only benefit someone who holds his guitar in the classic style. For the rest of us, it's in the wrong place to prevent belt buckle rash (my stomach actually performs THAT function!) but it kind of is a cool Gretschy feature. Apparently, some players bought the sales blurb because there are quite a few Gretsches out there with padded backs, but no mutes.Re: the Tone Twister, they are probably the least functional of any of Jimmy's ideas. A Gretsch enthusiast doesn't buy one of these for it's utility value as a vibrato, they get it for it's curiousity value as a cool Gretsch accessory. One benefit it DOES have is as a mute to prevent wolf tones from the strings between bridge and tailpiece. I have three different Twisters, a PAF, a Pat. App. no. and a gold Patent one.
