J Bass Section 4 - 4 - 

4.4

 

Installing the Tuners 

Each tuner consists of the tuner and hole collar.  The tuners are attached to the headstock with 

3/8”

 

wood screws (refer to Section 2.7). 

1.

 

Place a tuner into the headstock hole from the back. 

2.

 

Slide collar over the tuner shaft - secure the tuner to the guitar headstock with the supplied 
screws.  Remove the protective film if necessary. 

3.

 

Repeat 1-3 on the remaining 3 tuners. 

4.

 

Remove the collars and place a small amount of wood glue on the inside of the tuner hole (a 
toothpick might make it easier) and the collar – reinsert the collar.  Repeat on the remaining 
collars – let dry. 

4.5

 

Install the Strings 

Like most projects, there often several tricks that will make the assembly easier and your guitar better. 
Properly stringing your guitar is just one of those tricks.  Please review the 

following video: 

How to restring your bass guitar with John Carruthers: 

https://www.youtube.com/watch?v=-8uBYIwMevA

 

Although the video addresses restringing a guitar, the principles and techniques will help you string your 
guitar – as well as provide a visual for the stringing of your guitar. 

In summary: 

1.

 

Carefully uncoil each of the strings (4), ensuring that the stings do not have a kink.  

2.

 

Adjust each tuner so that the capstan slot is parallel to the tuner shaft. 

3.

 

Run the largest diameter string (E) through the upper hole in the Bridge base plate, carefully 
seating the string ball against the base plate. 

4.

 

Cut the string approximately 5” beyond the upper tuner (first) tuner.  Bend the wire 90 degrees 
at about ½” from the end and insert in the capstan hole of the first tuner.   

5.

 

Manually wind the string around the capstan in a clock wise direction and in a downward 
direction for 2 loops (check the video).  Continue to wind the string on to the capstan using the 
tuner keeping tension on the string so that the winding will be tight.  Continue tightening until 
the string is close to pitch.  The Setup section will address fine tuning. 

6.

 

Repeat steps 1 through 5 on the remaining strings (A,D & G), using the largest diameter string 
during each repeat.  

4.6

 

Installing the Strap Pins 

Secure each strap pins (2) in the pre-drilled holes with the supplied screws (item #9 on the material list, 
2ea, 1”).
