Of course guys like guitar virtuoso Carl Verheyen disagree. I started adjusting my Strats the way Carl suggests and I now can use my vibrato instead of having it tightened down flat to the deck and useless.
There's no doubt more than one way to skin a cat...and to set up a Strat...but Carl's method works as well as any and better than anything else I've tried.
The critical thing is angling the claw and then adjusting it so when you pull up on the arm the G string raises to a B flat, the B string raises to a C# and the E string raises to a F.
Some guys on the guitar forums say it's BS - but Carl's method makes my Strat's vibrato usable.
And I'll take the advice of a virtuoso like Carl over the advice of guys who spend more time on guitar forums than they do playing their guitar. Especially when that advice works.
