Watch the Amplitude Modulation Effects online guitar lesson by Chris Buono from Funk Fission
Taking the signal chain from the previous Time-Based Effects segments I augment that with the Cusack Tap-A-Whirl after the delay so I can manipulate the elongated repeats. I call this ‘post-producing’, which is simply me processing the near infinite feedbacks that make up my pad/cloud concept with various effects such as tremolo. In this case, I’m slicing up the feedbacks ala Reich through the Cusack trem by setting the Depth control to fully cranked to completely cut out the delayed signal as compared to when the signal is allowed to pass through. For another example I’ve included a track from Solitaire entitled “Floater” for an extreme case of amplitude-induced vertigo where I use the aforementioned signal chain albeit the trem is a Guyatone Flip Series VT-X. For the tempo changes I had to manually twist the Rate knob—that took a great deal of experimentation to get the right feel.
Some other effects I will use in my post-productions is extreme flanging (my vintage A/DA Flanger does the job well), ring modulation (instead of the Frantone Glacier I use the more tricked out Lovetone Ring Stinger), and sequenced filtering (featured in the next pair of segments).
