The finish looks in really good shape on yours. Based on the pickup position you must have an early '74. For some reason they moved the bridge pickup closer to the bridge sometime during the year. I love the classic look of the small pickguard with the ABR-1 but I gotta admit the Harmonica is pretty cool. Goofy looking, yeah. But I find myself doing a lot more palm muting when using it because it's just so easy and natural with that big wide bridge to rest your hand on. Interesting how small gear tweaks can change the way you approach your playing. Even so, I'm keeping the ABR-1 on my other SGs!
