From Guitar World 1992 Interview:

GW: In the studio, you'll often use many different guitar sounds within the same song. It must be tricky to execute some of your material live with the trio.

MORSE: One of the pieces I really enjoy performing live is "Highland Wedding" [High Tension Wires]-a tune that originally had a lot of overdubs. Dave LaRue and I worked out a live arrangement where he plays a polyphonic bass part that's a combination of the original recorded bass track and some of the guitar parts. I do a lot of switching back and forth between fingerpicked, arpeggiated chords and single-note lines. I also use the guitar synth, which helps create some interesting textures and fills out the sound.

GW: Do you use the guitar synth much when performing live?

MORSE: I use a volume pedal to fade the synth in during sections of certain tunes. You'll always hear the regular guitar signal-it's never actually replaced by the synth sound. Most people in the audience probably don't even realize I'm using the synth; they probably think there's someone offstage playing a keyboard.

GW: What guitar synth are you currently using?

MORSE: An IVL Pitchwriter II going into a modified Ensonic ESQM module. It tracks very well and has some cool string and Moog-type sounds that translate well through a stage rig. Many guitar synths sound much better through headphones than when they're blasting through a speaker. A patch that sounds very "sparkly" through headphones often sounds shrill and distorted through an amplifier or PA.
