The Voodoo Lab Tremolo re-creates the buttery, seductive tone of a vintage tube amp tremolo. This is accomplished by using the same lamp and photocell assembly found in many popular vintage amps. This pedal also features a slope control which lets you adjust the feel from a traditional soothing tremolo to a hard machine-gun stutter. Speed and intensity controls provide a wide range to include very slow and deep sounds. A volume control lets you cut or boost the output level. Now you can add warm, mind-bending trem vibes to any amp with the most versatile tremolo available.

Operation - We added two new controls to our Tremolo for even greater versatility. Depending on how youve set the controls you can get a perceived level change from the Tremolo. The Volume control is an output level trim which allows you to correct this to your desired playing volume. The Slope control varies the shape of the tremolo waveform. Set the slope all the way down for traditional tremolo. As you increase the slope, the rise and fall becomes sharper. When you turn it all the way up the off attenuation is increased for a better stutter sound.

Here are some possible settings:

1. Shimmer: set the intensity around 3:00 and the speed nearly all the way up.
2. Surf: try the intensity around 2:00 and the speed around 3:00.
3. Leslie: turn the intensity all the way up and set the speed to the desired tempo, probably between 12:00 and 2:00.
4. Stutter: turn the slope all the way up. Set the intensity all the way up and the speed as desired. Plugging into the input jack turns on the power to your Tremolo. To preserve battery life, disconnect the input cable when not in use.

External Power - The Voodoo Lab Tremolo can be powered externally with a regulated 9VDC power supply, eliminating the need for the internal battery.
The external power supply connector is a standard 5.5x2.1mm barrel with center negative.
