Never really got into the Firebird body shape, but I really love the headstocks on those things, the 2-tone colours really add to the coolness! They had a White and Black one with Gold hardware in Manson's a few weeks ago, not sure if it's still there, but even though I'm not a massive fan of the body shape I couldn't take my eyes off it! It has strangely alluring qualities, but the headstock is definitely the most interesting design feature for me.
Maybe one day I'll build something with a similar headstock, just a different body shape... :?
