The guitar in "Guitarp" was much easier to play than it may sound, it was the processing of the guitar that was more complicated.

Read on to find out how it was done.

The clip shows the progression in sequence, a different effect added after each 16 bar example.

Here's how it was done:
1. The basic guitar note(s) were played and clipped to 7 bars each. Fretted Synth guitar processor plug in was used for the distortion, compression, cabinet simulation (2x12 open back enclosure). Also clipped to eliminate pick attack; compression kept the tone a consistent level.

2. Delay and Chorus added with Fretted Synth plug in.

3. A step filter added for some modulation. It's subtle here, important later.

4. Second delay added to bring the single notes to 8 bars each, with some carry through another couple of bars.

5. Here's where the previous subtle effects come together. A pitch sequencer (arpeggiator basically) is used to play multiple notes based on the root note and chord - sus4, major and minor. So, the delay and chorus widened and added ambiance. The filter modulated the tone of the notes as they were played. The second delay provided more input for the pitch sequencer to arpeggiate. Voila! Seemingly complicated guitar part easily played with complicated processing.
