Chapter 2 Using the GR-20 with Guitar Effects

Here's how you can use your own effects unit and combine the sound of the guitar with the synth sound to create an even more
interesting range of possibilities.
The sound of the guitar's normal pickups will pass through the GK cable and be output from the GR-20's GUITAR OUT jack.
The sound that is processed by your effects unit can be connected to the GR-20's MIX IN, and internally mixed with the GR-20's
synth sound.
* Connect the output of your guitar to the normal pickup input jack of the GK pickup.
