Timeline is the name of a guitar pedal made by Strymon Engineering. I improvised this a few days after the pedal came out.
The Strymon Timeline is a very unique pedal in that it uses some very advanced DSP technology and allows some very interesting delay-based effects for whatever you input (in my case guitar).
I used the Timeline in this piece mainly for the sound effects on the actual notes. The loop is done with the Stereo Memory Man.
