SAG CIRCUIT
The Fender Shields Blender’s Sag circuit presents a
new and distinctive way to control fuzz using playing
dynamics, creating interplay between the player’s
touch and the voice of the fuzz—plus some explosive-
ly cool sound eects.
“Sag” is the eect on a signal when a tube amp or fuzz
pedal is underpowered (deprived of voltage). It’s
similar to the way a ashlight ickers and dims when
its batteries are running low, but here it’s the audio
signal that ickers and dims. The signal degrades (or
“ducks”) and regenerates, creating sonically interest-
ing fuzz eects with tremolo-like character.
Using dynamic-sensing circuitry, the pedal’s Sag
Footswitch and its two control knobs let the player control the amount of sag and when the sag is introduced; only applying sag
when the input signal reaches a certain volume—set by the TRIGGER control—and applying as little or as much sag (continued)
