About bridge & tailpiece measurements

Bridge and Tailpiece reference image

String spread is the distance between the centers of the outer strings on a bridge or tailpiece.

Saddle radius determines the arc formed by all the individual saddle heights, and is similar to the measurement of a fretboard.

Stud/post spacing is the distance between the centers of the mounting posts of a bridge or 'stop' tailpiece.

Tip: Slotting Tune-o-matic style saddles
Nut slotting files work great for metal saddles. Choose your file size as you would when slotting a nut: use the same gauge as the string, or a few thousandths larger. After filing to the desired depth, we suggest polishing the slot with Mitchell's Abrasive Cord to remove file marks and burrs.

nice replacement bridge

(Customer's Reviews)

Nice replacement bridge. I purchased this as an upgrade for my Gretsch Electromatic 6125 which had a non-adjustable bridge. The StewMac bridge is slightly narrower than my original but you can't really notice. I used a little Teak oil on the rosewood prior to installing it and that really brought out the detail in the wood.


Bridge replacement for Ibanez GB-10

(Customer's Reviews)

I have a 1978 Ibanez GB-10 George Benson model guitar. This is the first model year of this instrument and I have owned it since 1981. For years, I had wished I could do a precision intonation but could not because of the standard archtop-style wooden pin bridge. I did not want to destroy the integrity of the guitar by installing something that was non-standard, and also didn't know what the Tune-O-Matic style bridge would do to the guitar's tone.

Well, I went ahead and ordered this bridge, figuring there was little risk since the bridge floats (not permanently attached to the guitar body). When I installed the bridge, I swapped its wooden mounting foot with the old inlaid one from the original Ibanez bridge - it fit perfectly. I located the new bridge to center it based on the original bridge location (just mark the location of the old one before you remove it with post-it notes), strung the guitar up, tuned up, intonated the bridge as I would for any of my other guitars, and in my opinion it sounds better than before - maybe just a bit brighter, but still warm and jazzy.


Archtop Bridge

(Customer's Reviews)

This bridge was a perfect fit for an Epiphone Emperor II Joe Pass. It brightened the guitar right up. The fit to the top was great. I lined up the saddles to match the wooden bridge and placed it in the same position. Worked like a charm.


A good solution for a good price

(Customer's Reviews)

I had to replace a broken bridge on a cheap archtop. This bridge solved the problem and vastly improved the tone, for a low price. It needed to be sanded down about 1 mm, but it worked fine. Thanks, StewMac!

Intonation at last

(Customer's Reviews)

My old Gibson with the trapeze bar bridge was corroded and no individual string adjustment for Intonation.

This bridge plus a new tail piece allowed me to fix that.

I had to sand about 1/16ths inch off the bottom for the correct string height and it works great.
