EarthQuaker Devices Hummingbird V4 Repeat Percussion Tremolo Guitar Effect Pedal

The EarthQuaker Devices Hummingbird V4 is capable of producing everything from classic "'50s 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.

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. 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.

  • Three-way Mode toggle selects LFO range: position 1 is slow, 2 is midtempo, 3 is fast
  • Expression pedal control over Rate parameter allows for truly random amplitude modulation
  • JFET output stage boosts above unity gain to counteract perceived volume loss
  • With Depth set to zero, Hummingbird doubles as JFET clean boost
  • True bypass
  • Silent relay-based switching
  • New flexi-switch switching allows for momentary or traditional latching operation
  • Lifetime guarantee
  • Current draw: 10 mA

The Hummingbird should be powered a standard 9volt DC power supply with a 2.1mm negative center barrel. A pedal-specific, transformer-isolated wall-wart power supply or multiple isolated-output supply is recommended. 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. Current draw is 10mA.
