Used for Martin guitars that were made before 1994, also Larrivee, Blanchard, Garrison, Goodall, Ryan, Lakewood,McPherson, Santa Cruz and Taylor guitars.These also work with Collings guitars made prior to 2002.

PIN SIZE 2C for Martin Guitars :

5 degree guitar pin with .215" diameter at the top of the tapered shaft. If you own a newer Martin guitar, chances are the bridge pins are installed so the head of the pin sticks up about 1/4" above the bridge. Our size 2A pins will fit the same way. Size 2C is the same degree of taper but with a reduced shaft diameter (.215 " diameter at the top of the tapered shaft just below the skirt) so they will sit further down in the bridge (usually flush with the bridge but this is a situation where measuring a pin will be most helpful). In bone and fossil ivory.


IMPORTANT NOTES ABOUT SPECIFIC Guitar Make Pin Sizes:

Martin Guitar Pin Sizes:

Martin guitars prior to 1994 are always pin size 1T which is a 3 degree pin with a measurement of .210" diameter at the top of the tapered shaft. If somebody modified the instrument it may have a different pin size but Martin was extremely consistent with this size prior to 1994.

Martin went to a size 2A guitar pin sometime in 1994. The size 2A is .220" diameter at the top of the tapered shaft and is a 5 degree pin. Most Martin pin holes are drilled to .215" diameter at the factory so the size 2A, at .220", will stick up about 1/4" above the bridge. If your pins stick up about 1/4" above the bridge then the chances are high a size 2C will sit flush and you should buy size 2C. If your pins sit flush to the bridge the chances are high you should buy a set of 2A pins.

This is where measuring a pin that fits will come in handy and you can determine if you want a 2A (.220") or a 2C (.215"). It is our opinion that one should purchase the industry standard size 2A and if they stick up beyond your comfort level then you should have them fitted to the instrument by sizing the holes to accept the industry standard 2A. Any luthier worth his salt will have the 5 degree reamer and the skill to gently remove what will amount to dust from these holes for a perfect fitting of your new pins.

The modern Martin "Authentic Model" guitars take 2A. 230 UNSLOTTED guitar bridge pins. This is .230" diameter at the top of the tapered shaft and these bone or fossil ivory guitar bridge pins are unslotted.

Gibson Guitar Pin Size Guide

Gibson Guitar specifies a size 2A guitar pin for their instruments and we recommend this size. The chances are very high these will fit right. If you can measure the pins beforehand this will be helpful as some folks have found their Gibson pins to measure .210" at the top of the tapered shaft and have purchased size 1T which is that size.

The Gibson Epiphone almost always takes the 1.3T (3 degree pin but smaller in shaft diameter than the 1T) but Epiphone pin sizes can vary so it is best to measure the diameter at the top of the tapered shaft before buying.

These pins are slotted - that is normal. There is no extra charge if you want them to be unslotted. Just place your order and then email us through our contact page to request your order be filled with unslotted pins.

MEASURING GUITAR BRIDGE PINS:

If possible, it is VERY good to measure any pin that fits your guitar with a dial caliper or a micrometer so as to obtain an accurate reading of the pins that fit your instrument. The measurement you are looking for is the diameter at the top of the tapered shaft. This measurement should pinpoint exactly what size you need to order. The chart above, without the measurement, is very likely to work but the measurement is added security in knowing you have selected the right pin size for your instrument. Best to measure two or more pins that you know fit your instrument.

In addition, we send an instruction sheet with each set of pins that covers the installation and proper fitting of your new pins.

Also, if you wish, you can mail us a pin and we can tell you if we can make it. If it is a non-standard size we cannot make it and you will need to pay return shipping of $ 6 for your pin. Select a pin or pins to send that fit in all of the holes of your instrument. See our contact page for mailing instructions and contact us by email prior to mailing.

Not Sure What You Have ???

For any instrument you may need help with please email us through our contact page with the following information and we will help you as best we can :

We cannot assure you we will have the pin you need but we assure you we will try to help:

1) Make, model and approximate year of manufacture of the guitar you need pins for.

2) Is the pin slotted?

3) Measure the diameter of your pin at the top of the tapered shaft just under the collar. It is IMPORTANT that this measurement be done with a dial/digital caliper, or micrometer that will give you the dimension in decimal form to the thousandth of an inch (.210" for example). It is best to do this on a couple pins to get a common reading.

Lastly, PLEASE ensure your measurements are correct ! If in doubt, it's always best to purchase slightly over-sized pins and fit them to the guitar.
