The String Butler Installation Guide

To prevent damage to your guitar, Laplace recommends that this product be installed by someone qualified to perform basic guitar modifications.

Youtube Installation Videos

The following two videos, while not created by Laplace, do the best job of accurately and quickly explaining how to install the string butler.  Note that these videos don’t discuss the plastic washers that are included in the package because they are a new addition.  These washers are intended for placement between the device and guitar. They are optional, and you don’t need to use them.  They are provided in case you would like to prevent the String Butler from touching the headstock finish.

Step by Step Installation Instructions

Step 1: Decide how you will mount your String Butler.

Reference the following diagram for placement options.

While not shown, the String Butler can also be placed between the second row posts in the “Acoustic” orientation.

Note that this page will not provide instructions for installing with screws as this type of installation should only be done by a qualified guitar technician.

Step 2: Remove the strings from your guitar

Loosen all of the strings, cut them, and remove them from the guitar.

Step 3: Remove the hex nuts and washers from the two machine head posts to be used for holding the String Butler using a socket or wrench.

While loosening the nuts, notice how much force is required to free up the nut.  This will give you an idea of how tight the nut should be upon installation.  You don’t want to over-tighten the nut when you put them back on in step 8.

Step 4: Clean the top of the head stock to remove any dust or debris with a soft cloth and a cleaner which is safe for your guitar finish.

This step is particularly important if you are going to install the String Butler without the included plastic washers.  When used without the washers, some portion of the base of the device will rest on the headstock finish.  Any dirt, dust, or debris present could mar the finish.

Step 5: Place one plastic washer over each of the machine head posts. (Optional)

If you would like to isolate the String Butler from contact with your guitar head finish then you can use the plastic washers.  Note that if your guitar uses Locking Tuners then the posts may be too short to work with the washers.  If this is the case then you will have to use without the plastic washers, insure that the headstock is very clean before installation, and be sure to not over-tighten the String Butler which could create an impression in the headstock paint finish adjacent to the machine heads.

Step 6:  Place the String Butler on the guitar in the orientation chosen


Step 7:  Install the the metal washers and nuts that came with the guitar over the posts

Step 8:  Center the String Butler on the guitar head and, using a wrench or socket, gently tighten the nuts.  (Caution: Don’t over-tighten the nuts.  Reference how easy the were to loosen at step 3.  You want to use slightly more force to tighten then what was used to remove the nuts.)

For precise nut torque requirements reference repair instructions for your guitar or machine head manufacturer.

Step 9: Reinstall your guitar strings with them routed on the rollers as shown below
