Hi everyone,
How do you set up the bridge on your guitars with a 9 to 12 compound radius fretboard?
To you continue the compound fretboard somehow and make it even flatter? Or you just set it to 12?

Thanks!

Personally, I like a flatter radius at the bridge. It's probably 15" or something. It's really a feel thing.

I mean, there's room for personal taste here... But the theoretically correct answer is you continue the radius. 12th fret is the midpoint between the nut and the bridge, 24th (where the radius is measured) is halfway again, so it flattens 3 inches in 3/4 f the distance to the bridge. That implies a bridge radius of around an inch flatter, 13", when you get to the bridge.

Set the action based on the last fret, distance between the string and the fret.
Simple as that. I usually press the string to the first fret when I do that to eliminate nut height.

Re: string height:

If, for example, you were to set both 'E' strings to 1/16" at the last fret, then how high would you set the other four strings given the aforementioned radius (9.5 - 12?")

When I set the action I adjust all the strings to the same height across the fretboard. I don't use a capo or press the strings down at the first fret like John does - just a preference. If I should encounter fret buzz (especially on the low E,A & D) strings I just go slightly higher until the buzz goes away or becomes tolerable for my playing style. I use a Stewmac string action gauge to measure.

Dan Erlewine suggests (in his books) raising the wound strings slightly higher than the plain strings due to the larger elliptical vibrating pattern to avoid fret buzz.

There are no set rules - adjust the action to your taste and playing style. Experiment with different setups until you feel comfortable you've found the right one.

You set each string from the top of the last fret to the string (distance inbetween) with the first fret fretted. Start with 1/16" for each string and adjust to taste. You dont set it to a radius gauge, that would be redundant.
