This is a Jackson brand Floyd Rose type locking tremolo. It is an OEM product manufactured by Takeuchi Manufacturing, a model with the Jackson brand applied to the TRS-Pro. Black plated. Left-handed model. Although it is unused, it has been stored for a long time, so there may be fine scratches or dullness on the plating. Therefore, please refrain from bidding if you are sensitive or persistent. Unused items are rare and are hardly available anymore. There are no problems with use. The stud spacing is 74mm, so if the pitch matches, it might be a good upgrade from your current tremolo. The height of the inertia block is 35mm. This is a set of the main unit and the arm. Although it is unused, please refrain from bidding if you are sensitive or persistent. Instant purchase without comments is OK. It will be shipped via Letter Pack Plus.
