what's the difference between an original korean made original floyd rose and a german made original floyd rose?
Might look a bit different, I'm pretty sure they all function in the same way, at least the ones I've tried have.

ESP Eclipse CTM I
Dean 'Shards' Razorback
Chapman Guitars ML-1
Ibanez AEL40SE Acoustic
Blackstar HT-5 Mini Stack
EHX Metal Muff
EHX Small Clone
The real Original Floyd Rose is made in Germany; the korean made is built form cheap materials that won't last very long and is not original.
as far as i know its just quality difference, so ull still be able to do the same things like divebombs, pull offs, gargling/chirping, dime squeals, etc
