...on guitars that wouldn't look so good with a Bigsby. I've had a Firebird under my bed (literally) for a couple of years. Bought it for a ridiculous price, new, from the erstwhile Gibson-Amazon shop, when Gibson was being boycotted by Thomann, and Gibson was desperate to offload inventory. I love Tremelo/Vibrato arms, but I thought a Bigsby would not work with the Firebird's aesthetics, and would be expensive (especially if one factored in a Vibramate kit to avoid drilling holes.) Then I discovered the Duesenberg Les Trem: works on any guitar with a Gibson-spaced stop-tailpiece and takes 5 mn to install; reasonably priced (€89, with German precision steel enginering); on the Firebird, it works very well, and the guitar stays in tune; and IMHO, it looks absolutely fabulous! Not sure how good it would look on a Gretsch -- perhaps on a Corvette? Cheers, Dominique.
