compared with an orig Floyd ano po mas maganda gamitin and quality?
A lot of Ibanez owners (check Jemsite.com forums) rank the Edge/Lo-Pro Edge as equal to the Original Floyd Rose™ in terms of quality & tuning stability. Yung Edge Pro is Ibanez own design to avoid paying licensing costs per Edge/Lo-Pro Edge tremolo they build.
The Edge Pro II/III are Korean made using different metal and are OK in terms of performance, but not at the same level as the 1st 3 mentioned.
