Empress Effects reinvented its famous Tremolo pedal. The Tremolo2 has an all-analog signal path with incredibly powerful digital controls, including an innovative new multi-colored LED system for identifying up to eight presets. Also new is the control port which can be used with an external tap-tempo footswitch, an expression pedal (to control almost any function), or even with Empress' MIDI Box to recall presets or sync the pedal with time code. $249 street.
