I think the big argument you'll find is whether more, or less, mass in the bridge itself is "good" for tone - the Wilkinson looks a bit heavier. In the 70's more mass everywhere was always considered to be better, hence all the brass bridges, Alembics, solid granite guitars and so forth. I am personally guessing that light is better - Jeff Beck is using the Fender two-point, Andy Timmons uses a "Wilkinson/Gotoh VSVG Tremolo" which is their lighter "vintage" style, Julien Kasper uses a D'Pergo vintage style, Eric Johnson & SRV were vintage Fender all the way. There's a guy named Mike DeTemple who sells superlight titanium inertia blocks for $225 cause he says they sound better, there are other people who sell ten-ton brass & steel blocks cause they say they sound better.
My feeling is that a heavier, steelier bridge might give you more highs and sustain, and a lighter bridge may allow proportionately more wood into the tone, hence a warmer sound. Heavier in general seems to work best in high-gain situations, all those 80's solid-maple B.C. RIch & Charvel hair-metal guitars.... There are so very many variables - string gauges, number of springs - 4 set loose, 3 set tight. Heavy metal? Ventures? Fusak? Barry Manilow covers? Gaak...
I'm building a Warmoth seven-string with one of these:
It seems to be conventional weight, two-point mounting. For added confusion, here's just the two-pivot-point Allparts page:
I am not an expert whammyhead, I've avoided them for thirty years... but now I want one, darn you Jeff Beck and "Nadia". My guesses are just based on the kind of equipment used by the whammyhead guitarists whom I really admire - Kasper, Beck, Timmons, Johnson. Gee Whiz? Not a locking Floyd among them?!? :icon_biggrin:
