Gary Pihl's primary guitar is a Jackson. His signal path goes from the guitar to the Sustainor, and from the Sustainor's send to the MXR Pitch Shifter, then to the Delta Labs Effectron (Gary's version of the Hyperspace Pedal), the left channel of the PGE 2 and back to the Sustainor's return. From the Sustainor's output, the signal goes to the right channel of the PGE 2, then to the Smart Gate, Stereo Chorus/Delay and finally the Stereo Echo. Gary's Stereo Echo has been modified so that he has added control over the echo volume. By activating a footswitch, he can set the echo volume to -10 db which is great for rhythm playing. There is a yellow LED to the right of the printed "Echo Vol" that indicates its use.
