The Earthquaker Devices Hummingbird is a modernised and modified tribute to the legendary Vox Repeat Percussion tremolo. This version of the Hummingbird features a JFET preamp which gives you more headroom, while its Depth and Level controls make it more versatile and give it a signature voice. The Hummingbird's mode switch lets you go from snail slow to ring-mod fast and everywhere between. Combined with the option of attaching an expression control jack for the rate, you're left with an incredibly versatile pedal. If you're looking for a tremolo pedal that can do it all, look no further than the Earthquaker Devices Hummingbird.
