The Intonator

About This Item

Easy way to get accurate intonation! The Intonator finds the correct location for placing the saddle on a flattop guitar bridge.

Dan Erlewine designed it to use before cutting the saddle slot in new bridges, or when you fill and reslot an existing saddle. The old method of placing dowels or pins under the strings isn't accurate because the strings pull the dowels out of position. This doesn't happen with The Intonator, because the solid brass bar anchors the adjustable brass saddles while you fine-tune them.

Each saddle includes concentric brass bushings to be added or removed for setting precise string heights. Simply turn each thumbscrew until the intonation is just right, then mark the saddle positions on the bridge. You now have accurate guides for routing for a new saddle, and you know the guitar will play in tune up and down the neck. You can test the intonation by playing the guitar while The Intonator is in place.

Concentric bushings build each saddle to the correct string height
Support bar is arched for the upper bridge surface
String intonation is precisely tuned with thumbscrews

The Intonation - easy augmentation

By

Verified Buyer


I used the intonator on a couple new builds but was frustrated that it seemed geared for a 2 1/8" string spacing at the saddle, which is simply too narrow for the finger-style guitars I build - the bridge pins simply wouldn't allow for more than 4 of the tools L-shaped arms at a time without half of them being at odd angles. To use it for guitars with a 2 5/16" thru 2 7/16" spacing, I had to set it up, do 3-4 strings, then reset it for the remaining strings - not too difficult but tedious and error prone IMHO, though the results were still pretty darn good.

Simple fix - I bought some 3/16" x 1/4" rectangular brass bar stock and cut, drilled and radiused a half dozen additional support bars with holes to support wider spacing up to 2 1/2" in 1/16" increments. Now I just use the bar drilled for the desired string spacing and follow the instructions that came with the original - after another half dozen builds using the augmented tool I love it and have gotten nothing but praise for the "spot-on" intonation it, used along with StewMac's Saddle Routing Jig, allows me to deliver.

Thanks guys - another winning combination that has simplified my life and cut the pucker factor in my guitar building efforts!

The Intonator

I like to have my acoustic guitars and those of my customers intonated accurately with a Strobe tuner. The effect is startling for those who have never heard it before, and especially for those who have never heard a 12-stg. done right.

This gaget makes the job go faster and without the usual fuss. "Close" is for hand grenades and horse shoes - not for musical instruments!

It's not perfect, but if you're worth the name "Luthier", you should have no problem making some
extra parts and minor modifications to make the job go easier on specific guitars. It a worthwhile
addition to a serious toolbox.

Works for me

I used this on a new bridge on a ‘55 Gibson LG-3. Didn’t have much trouble getting it on. Worked very well. What a pleasure it is to play a guitar that is so “in tune” with itself.

FINALLY!!!

Verified Buyer


Been "eye-ballin'" this thingy for quite a while, and finally 'pulled the trigger' on it. It'll have it's first use coming up shortly, and I can rest a LOT easier that after the removal and replacement of the original bridge with one shaped from a 'Stewie' Ebony blank, I'll know where to properly locate the new Saddle slot! This tool will decrease what I refer to as the "SWEAT FACTOR"! Thanx folks. Also just ordered your Bridge Plate Saver tool for this same instrument. Gb bg

I haven't had an opportunity to use it yet, but it looks well made and should work admirably! Thank you for inventing it!

I use a wooden shish kabob skewer w/ a flat spot sanded on the bottom. Works perfect & there's no risk of dropping this contraption & any of the loose pieces on a new finish.

great idea....but......

By

Verified Buyer


The good news is that it will help you intonate your acoustic and it does that pretty well.
The bad news is that you need 4 hands to help get it in place and setup....what a chore! The little cylinders are a great idea but getting them in place without disturbing the other ones or having ones fall off is tough. Put on your thinking caps StewMac....its a great concept......

Slipping thread

By

Verified Buyer


This could be a great tool however one of the threads on mine slips so have to set five strings then remove one nut and use it for the last. It also has a tendency to rise above the bridge pins so I had to turn some square topped ones to seat it against. It does work but we fell out a few times and I'm not sure I've forgiven it yet!
