Blowing smoke, all it is. As was stated, it's a nice concept for helping with butchered feet, but really now, the brass thing is getting absurd.
Brass truss rod covers, cavity covers, knobs, jack plates, Floyd arms, and switch tips will be the next tone-enhancing miracle discoveries.
Along with brass strings and frets. Then we'll be back to brass nuts, brass pins in the brass locking tuners, brass Floyd nuts, brass screws, all-brass Floyds (including the saddle blocks), brass inlays, brass binding, brasswood fretboards, brasswood bodies, brass cables, brass amps, brass speakers. I tell ya it'll look like some Steampunk masturbatory fantasy :lol:
