The greenest tremolo around.
Welcome to your new Hummingbird Repeat Percussion tremolo! The Hummingbird is a choppy, sawtooth tremolo modeled on the vintage “repeat percussion” unit, and similar to those found in old Valco and Vox amplifiers. It is capable of producing everything from classic “50’s style” shimmering tremolo, to a synthy, delay-like chop that turns your signal into a burst of short pings, and on through to near ring modulation speeds. By simply choosing between modes 1 (slow), 2 (mid-tempo) or 3 (fast) and adjusting the rate and depth controls, you will be able to unlock a whole new world of amplitude modulation. The Rate is also expression pedal accessible, to allow instant changes on the fly. Using an expression pedal opens up the possibility of true random amplitude modulation! In addition to the modulation, the Hummingbird has plenty of clean gain on-tap, allowing you to either boost or cut the signal using the level control. If the Depth is turned to zero, the Hummingbird will become a JFET clean boost! The Hummingbird is all analog, true bypass, and handmade one at a time on a gilded cloud in Akron, Ohio.
Depth: Controls amount of modulation from "barely there", to full signal chop at full bore.
Rate: Controls the speed of the LFO. Clockwise for faster, counterclockwise for slower.
Level: Controls the signal input level, which ultimately controls the output level. Clockwise for more, counterclockwise for less.
Mode: A three-way toggle switch selects the range of the oscillator. Mode 1 is slow, mode 2 is mid-tempo, and mode 3 is fast.
Expression Jack: Use an expression pedal to adjust the rate with your foot! When an expression pedal is in use, the Rate control is defeated. EarthQuaker Devices recommends the Moog EP-2 expression pedal.
EarthQuaker Devices take a standard 9 volt DC power supply with a 2.1mm negative center barrel. The company always recommends pedal-specific, transformer-isolated wall-wart power supplies, or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains, and non-pedal specific power supplies do not filter dirty power, and let through unwanted noise. Do not run at higher voltages! Current draw is 10 mA.
