This is a synchronized tremolo. It's an outlet part. Although it's unused, it's an outlet item, so there may be scratches, dullness, rust, etc. from transportation and storage. Please do not purchase if you are looking for a pristine item. ※The image is a sample. The color of the spring hanger and other things may vary. It's inexpensive, so please understand that it's not as perfect as a Gotoh product. The stability of tuning, etc., can be resolved through experience with synchronized tremolo setup. I find it useful for restoring and customizing inexpensive guitars because it's cheap and reasonably functional. It's the type with the light and quick sound of a pressed saddle. The spring hanger size is different from the standard, so it often won't fit bodies with shallow cavities. When replacing it, we recommend using the spring hanger that was originally on the guitar. The tremolo itself is about the same size as a standard synchronized tremolo. We recommend that those who are particular use brand-name products.
