When playing single-note fuzzy riff, I usually try to add the octave down FX.
In my case it's usually Digitech Whammy.
Well, it's not a good thing in every situation.
But when it fits, it's great!
Of course, you can ask your bass player to play along with you instead of Whammy.
But, who needs a bass player anymore?
Whammy plays so tight even it has several miliseconds latency!
Whammy has so much better tone overal even it's digital.
Whammy knows what I want to play even before I play.
Whammy has perfect timing, like me...
Whammy can play more than 4 notes.
Whammy doesn't need 8x10 cabinet.
Whammy can't get drunk.
Take it easy and may the muse be with you!
