Earthquaker Hummingbird V4 Tremolo Pedal

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 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.

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!

• RateThis adjusts the speed of the oscillator. Faster clockwise, slower counter clockwise.
• DepthThis adjusts how much the oscillator affects the signal.
• LevelAdjusts the output volume
• Modehree way toggle switch which selects the range of the oscillator.
• Expression JackUse an expression pedal to adjust the rate with your foot!
