Earthquaker Hummingbird V4 Repeat Percussions - Tremolo


Sold Out

Product Details

Welcome to your new Hummingbird Repeat Percussion tremolo! The Hummingbird is a choppy, sawtooth tremolo modeled on the vintage ͞repeat percussion͟ unit and similar to those found in old Valco and Vox amplifiers.  It is capable of producing everything from classic ͞50s style͟ 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
