Power
Requires an isolated center-negative 9V DC supply rated at least 250mA; the supply is sold separately.

Independent shopping perspective
Built around circuit-accurate 1176LN compression modeling, the silver UAFX 1176 puts several compression behaviors on a pedalboard. Single delivers normal compression, Dual runs two modeled compressors in series, and Sustain uses parallel compression for extended sustain; an all-buttons-in setting handles extreme compression. Attack, Release, Input, Output, Ratio, and Blend give direct control over response, recovery, level, amount, and dry/compressed signal balance. Choose true or buffered bypass to suit the rig.
