Ive been using a radius gauge lately to help me dial in the action and bridge saddle heights, its really been making setups easy once I got used to using it...I lay it across the strings, it helps if you have a good light source behind it, and then I raise the saddles till I cant see the light reflecting off the string(under the gauge), getting all of them in a nice uniform arc/radius.

I made this one from a template I found online. And for the record, Im probably not using this for its intended purpose, but I find it works quite well...thought Id share.


It kinda helps if you get both of your E strings as low as you can first, and then raise or lower the middle strings to complete the arc/radius.

BTW its easy to figure out what radius your neck is just by eye balling it with the gauge, no need to take the strings off...just sayin...in case you were wondering:
