Re: trem help
You need to measure very carefully.
First of all, set the saddles as far forward as you can. This will optimise your intonation range.
Measure the distance from the front of the top E saddle to closest edge of the pivot knife-edge on the bridge plate. Call this value "t"
Measure the diameter of the waisted section of the pivot post. Call this "d"
Measure the distance from the nut to the exact centre of the 12th fret's crown. Call this "s"
The longitudinal location of the bridge posts (L) relative to the nut is then given by this equation:
L = 2s - (0.5d+t)
Mark a line at this point on a piece of masking tape placed at the approximate location of the pivot posts.
The two pivot blades are usually different; one is usually U shaped, the other straight to accomodate slight registration errors.
Measure the distance between the bottom of the U blade and the midpoint between the D and G saddles.
With a straightedge, find the midline of the fingerboard and mark it on the first line you drew on the masking tape. Alternatively, if the fingerboard is narrow, use a couple of lengths of patch cable as string substitutes in the top and bottom E positions and thread these through the bridge to "guesstimate" it's position. This will allow you to get an idea of the fingerboard edge clearance. Once you have assessed this, you can mark the centreline of the bridge (between the D and G saddles).
Once you have this marked it is easy to place the centre of each pivot post location on the line going across the body in front of where the bridge will be.
Best of luck...
