l, l 1 + 1 That article included a number of diagrams and all the math needed to make bridge height calculations for most styles of flattop guitar.

We are doing this now to help flush out any fret or nut issues that can be taken care of now before we go any further and we can get a string action measurement so we can calculate how much to lower or raise the saddle in the bridge to set the action of the guitar to its optimal height later on in the process. ne 0.056 r f, h For the High E and B string, we like to have about .010″ of clearance. * To straighten the neck you want to check how much relief there is first. h - For the D and G strings, .017″ of clearance above the fret. You can check out our fret level article that shows you step by step how to go about one https://guitaristlab.com/the-fret-level-un-dressed/. jb After the nut slot heights have been adjusted to their desired levels, you want to play the instrument and go through everything to make sure it is sounding and playing as well as it possibly can. - To adjust the action, you need to raise or lower a part of the bridge known as the saddles (the parts just in front of the bridge where the strings sit). - And that concludes our classical guitar setup. The second issue you want to check out before you start the setup is to see if there is any structural damage. t, l l Note again that neck angle should be specified in increments that can be accurately cut in wood. jb = This means that in order to bring the action of the strings down 1/64″, you will need to remove 2/64″ at the saddle to achieve this. jb Note that a collision or a lack thereof is not necessarily a good or bad thing, but must be accounted for in the construction of the instrument. 2 Last updated: The “golden ratio” for lowering the action on a bridge saddle of an acoustic instrument is 1:2. = 2 Then a fret level and crowning would need to be done to them before moving on. - You want to measure from the top of the 1st fret to the bottom of each string with a feeler gauge to get the action at the nut. l sin 2, h jt The calculator can be used to calculate this as well. Subtract a reasonable amount of saddle exposure from the total and that will give you the height of the bridge itself, without the saddle. 1 + After we mark the lines on the saddle and make sure we will have enough left sticking up out of the bridge slot, then we can sand down the bottom of the saddle.

The setup for classical guitars is basically the same as those for steel strings or electrics, but there are a couple of things you have to take into consideration before you tackle the setup.
