---◎Important◎--- Many people are concerned about the width of the string slots, so I have removed the bridge from another 90s Gibson guitar I own and posted comparison photos of the slots. The bridge with the duller color is for comparison purposes, and has been using .009-.042 gauge strings since the beginning. The 2nd to 4th photos are additional images. This bridge is for comparison purposes and is not for sale. ---◎End of Additional Explanation◎--- ---◎↓The following is the original description from the listing↓◎--- I am selling a Gibson ABR-1 bridge. The profile of this item is as follows: ・This was originally installed on a Gibson L-4 full-acoustic guitar that I purchased new from a musical instrument store in the 90s. ・I ordered a wooden bridge at the same time as the purchase, and replaced it a few days later when the wooden bridge arrived. I have kept this bridge separately for about 30 years. ・Because of this background, the actual usage time is estimated to be within 50 hours at most. ・The slots have been cut. The slot size is as mentioned above, as it was installed on a Gibson full-acoustic guitar, so it may be thicker than the typical electric guitar sizes of .009 or .010. -------------- I have included many photos, so please check them carefully. Shipping will be via Rakuraku Mercari's "Nekopos" service. Thank you.
