The EarthQuaker Devices Hummingbird V4 Repeat Percussions Pedal 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 an 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!

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 the signal.

*Note: Do not run at higher voltages.
