Watch the Wet Swells online guitar lesson by Jeff McErlain from Guitar Effects Survival Guide
I love when we can use the guitar and effects in such a way that it doesn't sound like a guitar. Here is one of the easiest and prettiest ways to do that. The key here is the delay and volume pedal. The volume pedal removes the attack of hitting the strings and produces something more similar to a keyboard or bowed instrument. The great Alan Holdswoth is a master at this. I was first exposed to him using this sound on the IOU record specifically the tune "Shallow Sea".
