Well, this is a first time I installed this Gotoh trem, instead of usual OFR, FR1000, or Ibanez plethora of Edges.
It outperforms every mentioned double locking trem, except Schaller Lockmeister. Keep in mind, I am referring to Schaller LOCKMEISTER, with printed logo, not Schaller LOCKING with ingraved logo.
The only downside of this trem is it only comes for 14" radius fretboard guitars, most of mine are 12" or 16" radius fretboards. Schaller Lockmeister on their site can be configured for any nut size, nut radius, and trem radius. I really don't know if Gotoh can adopt that style of sale. But it stays in tune forever, flutters like crazy, dive bombs, pulling up, and still being in tune. Hats off!
