Göldo Mod. Hardtail ST-Style Bridge

Not as advertised, the screws on the backside are not countersunk due to the thinner sheet plate i guess.
No sustain at all or at least worst than the cheap original on a Bullet Mustang.
Worst of all is that if one touches it while playing the intonation goes... The saddles move both to the sides and in/out.
Lastly, on mine the small allen screws on for adjusting the height loosen while playing so the string buzzes, A and low E strings that is...
