Rare! Floyd Rose FRT-4 This is a Japanese-made Floyd Rose from the early 1980s. A rare FRT-4 Upgraded with a zinc alloy block, approximately 42mm. There is rust and scratches, but it's in decent condition. This is being sold as part of a decluttering effort. The original locking screws were severely rusted, so they have been replaced with aftermarket ones. The arm is the same type, but black. Please be aware of this. The sustain block will be removed for packaging. They are traded at high prices overseas. I'm turning 60 and won't be using it, so I'm selling it as part of a decluttering effort. I'm offering it at a low price.
