Gotoh Floyd Rose type bridge. I installed it on a guitar about a year ago after purchasing it new, but I rarely played the guitar. I removed it recently because the guitar was relegated to parts. I believe all the parts are included, but everything in the photos is what's available. *Except for the main body and arm, the parts are unused. *Lock nuts were originally sold separately. The block is 40mm. There is a slight paint chip on the part of the plate that contacts the studs (see photo). It's in good condition, but it's not new, so please consider this if you understand. Reference information: Previously, individual blocks were not often sold, but now aftermarket 33mm and 36mm blocks are sold on Amazon. Also, because I don't like the angle of the arm and the torque adjustment of the set screws, I replace the arm with a RED BISHOP MAGIK-ARM for Floyd Rose (specifically for Floyd Rose) when using this bridge. Thank you.
