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. 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! The Hummingbird is all analog, true bypass and handmade one
at a time on a gilded cloud in Akron, Ohio.
Controls
Depth: This adjusts how much the oscillator affects the signal. All the way
clockwise produces a full chop, all the way counter clockwise produces no
chop and the Hummingbird can be used as a simple JFET booster.
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.
Rate: This adjusts the speed of the oscillator. Faster clockwise, slower
counterclockwise.
Level: Adjusts the output volume
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.

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!
Current Draw: 10 mA
Input Impedance: 50 kΩ
Output Impedance: <10 kΩ
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.
Warranty
This device has a limited lifetime warranty. If it breaks, we will fix it. Should you
encounter any issues, please visit www.earthquakerdevices.com/warranty.
