EarthQuaker Devices Hummingbird V4 Repeat Percussion Tremolo

Add to Cart
The Hummingbird repeat percussion is a special treat for fans of old-school tremolo with a serious twist. Believe it or not, this chopped and screwed effect comes from a few select vintage amps made famous by Valco and Vox. We all have some working knowledge of Vox's history but you may know Valco by their many pseudonyms: Supro, Airline and National. As a departure from your typical sine-wave tremolo unit, the repeat percussion effect delivered a hard-edged sawtooth tremolo that could emulate long delay, digital stutter, ring modulation and everything in between. The Hummingbird gives you three selectable speed modes that you can further alter with Depth and Rate. It's great for adding fun rhythmic elements to your playing or driving your guitar signal into madness. As an extra dose of versatility this pedal makes a solid clean boost when you tune out the depth control all the way. If you love tremolo but have been yearning for something more, spread your wings and take flight with the Hummingbird.

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. Simply choosing between modes 1 (slow), 2 (mid-tempo) or 3 (fast) and adjusting the rate and depth controls will unlock a whole new world of amplitude modulation at your feet. 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!

Controls

1. Depth: This adjusts how much the oscillator affects the signal. All the way clockwise produces a full chop, all the way counterclockwise produces no chop and the Hummingbird can be used as a simple JFET booster.

2. Mode: Three way toggle switch which selects the range of the oscillator. Mode 1 is slow, Mode 2 is mid tempo and Mode 3 is fast.

3. Rate: This adjusts the speed of the oscillator. Faster clockwise, slower counterclockwise.

4. Level: Adjusts the output volume

5. 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. We recommend the Moog EP-2 expression pedal.

Flexi-Switch® Technology

This device features Flexi-Switch® Technology! This relay-based, true bypass switching style allows you to simultaneously use momentary and latching style switching.

  • For standard latching operation, tap the footswitch once to activate the effect and then tap again to bypass.

  • For momentary operation, hold the footswitch down for as long as you’d like to use the effect. Once you release the switch the effect will be bypassed.

Since the switching is relay based, it requires power to pass signal.



Power

This device takes a standard 9 volt DC power supply with a 2.1mm negative center barrel. We always recommend 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 as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!
