OK I could have titled that way better, but it wouldn’t be me. I recently took delivery of an assortment of Gretsch knobs from our resident doctor. So I wanted to replace a plastic Gibson 3-way knob with a knurled one from Gretsch(known as the Armygirl mod) but I didn’t love the result. Looked around in the stash and there were a few spare Gretsch strap buttons. It was a perfect fit and looks way better on this particular guitar(Epi Firebird).
