Thanks to everyone! I happen to agree with the majority, please see the site for the results :-) I will still keep the poll open, but I decided to disclose the results due to reasons I explain on the site.
In place of it, I have added a new poll with different tremolo spring block materials: aluminum, brass, and steel. To make it worth your while, and to make things more interesting, I will raffle off a black fixed bridge (i.e. a set of 6 tuners) to the voter who can identify correctly which is aluminium, brass and steel respectively. I will announce the results on Feb 1, 2009. If more than one has a correct answer, the coolest project will win, so please let me know how you plan to use the bridge for if you win it. Submit your entries via e-mail only please.
