I blocked my Amer. Strat last week and did use the five spring arrangement and did not screw down the claw. Remember that their are both silver and black colored springs. Amer. Strat uses black and I would not mix. I found a really great article on "Hard Tail" options (pg 78) in The Fender Stratocaster Handbook by Paul Balmer. He had a great way of measuring the block angle using a digital caliper. My Amer. strat has an angled block and it is important to get the angle correct to maximize contact. Love the change.

Any idea what trem block is on a 2010 Am. Dlx? It just seems very small... Is it worth replacing it with a Callaham or the brass one?

Cedarblues,

Just for my education, what is a callaham?

what is the purpose of putting 5 springs on the trem? sorry, noobie here..

i own a stratocaster floyd rose 2 but only has 3 springs..

putting extra springs makes the guitar sound much better?
