From the vendor
Our take on the EQD Hummingbird V2 – the trem is a choppy, sawtooth tremolo based on the vintage VOX Repeat Percussion pedal. Giving you the ability of producing everything from classic 50’s style shimmering tremolo to a more modern, synth fueled, delay-like chopping machine short cuts, bordering on ring modulation.
An important note: Ensure you use a genuine 2N6027 – otherwise you?ll get no effect. Trust us!!
