MEASURING: 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, along with the pin information below should pinpoint exactly what size you need to order. The information below, 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 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.

Below the information on sizes will be additional information on specific guitars that you will want to read.

PIN SIZES

Pin SIZE #1 :

3 degree pin with .210" diameter at the top of the tapered shaft. 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. These pins are slotted the full length of the tapered shaft and TO the skirt but NOT through the skirt (See photo at top of this page). If you need UNSLOTTED pins please email us through the contact page for availability on the size and inlay type you desire (price is same for slotted or unslotted).

Pin Size 1T :

A size 1T is simply the same as a size 1 pin (3 degree and .210" diameter) but these are slotted THROUGH the skirt not just TO the skirt as it is on a size 1. You can buy one of these by purchasing a size 1 pin set on this website and then you can email us after your purchase, through our contact page, and let us know the set needs to be a 1T ( to be slotted through the skirt -see photo at top of this page).

Pin Size 1.3T :

This is a 3 degree pin with the slot through the skirt like the size 1T pin but with a slightly smaller shaft diameter. These are .203" diameter at the top of the tapered shaft rather than the .210" of the size 1. If you want a size 1.3T just order a size 1 on the website and then email us through our contact page to let us know you want the 1.3T. The 1.3T is only available in bone.

PIN SIZE # 2A :

5 degree pin with .220" diameter at the top of the tapered shaft. For modern Martin guitars (after 1994) and Gibson guitars. For Martin guitars see also our size 2C (listed below) for additional information to help you select the right pin and then scroll down further on this page to read the details under " Martin Guitars ".

These pins are slotted the full length of the tapered shaft and THROUGH the skirt. If you need an UNSLOTTED pin please email us through the contact page for availability on the size and the inlay type you desire (price is the same for slotted or unslotted).

The recent D28 as 1941 Authentic models take a size 2A unslotted pin.

PIN SIZE # 2C :

5 degree 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).


IMPORTANT NOTES ABOUT SPECIFIC MAKES :

MARTIN GUITARS :

Martin guitars prior to 1994 are almost always size 1 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 some time 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 recent D28 as 1941 Authentic models take a size 2A UNSLOTTED pin. If you need an UNSLOTTED pin please email us through the contact page for availability on the size and the inlay type you desire (price is the same for slotted or unslotted).

GIBSON GUITARS

Gibson Guitar specifies a size 2A 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 a 3 degree pin.

The Gibson Epiphone usually takes the 1.3T ( 3 degree pin but smaller in shaft diameter than the 1T) but Epiphone pin sizes vary so it is best to measure the diameter at the top of the tapered shaft before buying. If you need a size 1.3T then purchase a size 1 on the website and then email us through the contact page to let us know you need it to be size 1.3T.


For any instrument you may need help with on selecting the correct size 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 and does the slot continue through the skirt or stop below it?

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.

End Pin Size
Our standard end pin has a diameter of .315 " at the top of the tapered shaft and .250 at the bottom. This fits most guitars including Martin. It is
exceedingly seldom this size does not fit.

Strap Button Size
The strap button can be fitted to any instrument that uses this style of neck strap button. The final bit of class for those who want a totally
tricked out guitar. The way these are made it is necessary to have an inlay.
