Wiring a 1/4" Stereo to 1/4" Mono Cable
« on: January 23, 2006, 06:01:27 PM »
Note: Series I/II instruments were supplied with prewired stereo jacks until about 1988. This is only useful if your Series I/II 1/4 is prewired in stereo.
 
Instrument end: Tip Ring and Sleeve plug
Preamp end: Tip Sleeve plug
 
Preamp end: The tip of the preamp end goes to the signal wire of the shielded cable.  
 
Instrument end: uses 2 resistors of approximately 20KOhms (10K or 22K are OK). Connect a 20K resistor to the tip terminal. Connect another 20K resitstor to the ring terminal. Take the free ends of the resistors, connect them together then connect them to the signal wire of the shielded cable.  
 
You can now hear both pickups without using the power supply.
