Question for Jeff Seitz or anyone who knows the answer

[Mario]

I'm not sure this question was asked before in this forum and I apologize if it was.

I was always intrigued by what I believe to be a guitar sound in "Darkness". I'm talking about the sound that carries the harmony throughout the song. It sounds so much like a mix of electric guitar, harmonics and piano! Was that generated by Andy's Roland Guitar Synth? (Was it the G303?) Or are those two separate tracks of guitar and piano, mixed together? Or something else.

I just love that sound!!

Thanks in advance for any info!!
