Introduction Back in 2005 we released our first pedal, the Tremolo. It was one of the first tap tempo tremolo on the market and, to this day, remains as sought after as when it was first released. We have built on everything we have learned over the past eight years, and are proud to release the next generation of tremolo, the Empress Tremolo...
Quickstart Plug your guitar into the lower jack on the right side. Plug your amplifier into the jack on the left side. Plug a 9-12V power supply into the power jack on the left side (2.1mm barrel connector, negative tip). Set the mode switch to "knob," the waveform switch to "tube,"...
Tap Tempo Mode In tap tempo mode, use the "tap|preset" stompswitch to enter a speed for the tremolo. The tremolo will change to the new speed after 2 taps and will average the speed of the last 4 tap times. Use the ratio knob to change the ratio of tapped tempo to tremolo tempo.

To load a preset, use the "tap|preset" stompswitch to scroll through presets sequentially. The LEDs will blink indicating the preset is ready to load. Press the bypass switch while the LEDs are blinking to engage the new preset. To save a preset, set the Tremolo to the settings you want to save.
Control Port The control port jack allows the Empress Tremolo to be controlled by a multitude of devices. The pedal ships configured to accept an expression pedal. Please see the "Advanced Configuration" section on how to configure the control port for the device you want to use. Control Voltage (CV) With CV control, the Empress Tremolo responds to CV signals from...

Expression Pedal Each parameter, with the exception of the mode switch, can be controlled simultaneously via the expression pedal. To control a parameter with the expression pedal, move the parameter's knob to the desired heel setting, then hold down the save button and move the knob to the desired toe setting, then release the save button.

MIDI Configuration The Empress Tremolo allows all of its parameters to be controlled via control change messages, it's presets to be selected with program change messages, and its tempo controlled with MIDI clock messages. To use MIDI with your Empress Tremolo , you'll have to do the following: 1.

Recalling a preset via MIDI (Program Change Messages) You can activate a preset by sending a MIDI Program Change message. For example, sending a Program Change message of 7 activates preset 7. MIDI Clock (aka MIDI Beat Clock) The Empress Tremolo will respond to MIDI Clock messages.

Control Change Messages The Empress Tremolo can be controlled with MIDI control change messages. Below is a table that shows which MIDI control change channel controls each Tremolo parameter. Tremolo Parameter CC #: Note: Depth Sending a value 0 would be equivalent to the knob completely counter clock-wise, sending 127 is Rate | Ratio...

Waveform Phase A Value of 64 has the waveform in phase. Higher values move the waveform ahead relative to the beat and smaller values move it behind. Tap Switch Sending a value of 127 simulates the switch being pressed. Sending a value of zero simulates releasing the switch.
