JEM Section 4

 

- 2 -

 

Insert the Output Jack (item #9 on the material list) through the 
tunnel in the end of the Body; secure with supplied nut (align the 
jack contacts to allow for easy soldering prior to tightening). 

1.

 

Check the length of the Output jack wires – if they extend 
beyond the Body, it may be easier to solder the wires to 
the jack prior to inserting in the Body.  Ensure that the 
wires run through the nut (inside the jack pocket). 

2.

 

Solder the signal and ground wires to the jack (see Figure 
4.2) (Note: if the signal wire is shielded, solder the shield to 
the ground terminal on the jack). 

3.

 

Install Output jack cover – pearled surface up. 

4.3

 

Installing the Strap Pins 

Secure each strap pins (2) in the pre-drilled holes with the 
supplied screws (2ea, 1”). 

4.4

 

Assemble Pick Guard, Bridge and Neck to 

Body 

Refer to Figure 4.4 during this section.  Noted wiring colors are 
typical and may vary.

Figure 4.4 Body Assembly Reference 

Tip

if the wires are not red, black & white, the 2 wires soldered to the Volume 

potentiometer case are the ground wires; the remaining wire is the signal wire: run the signal & 1 

ground wire through the output jack tunnel and the remaining wire through the tremolo tunnel
