Brings modern and classic pitch shifting styles together with fuzz and modulation to create the ultimate octave pedal. Featuring four separate octave divisions: one octave down, two octaves down, one octave up, and two octaves up -controllable in the mix. Your dry signal gets its own level control as well, so you can dial in the perfect blend of pitch-shifted tones. Also equipped with a fuzz that’s inspired by the classic MXR Blue Box™ Fuzz. When used with the sub-octave signals, the fuzz sounds thick and subterranean. Over the higher pitched signals, its searing and synth-like. Then there’s a dual-mode modulation effect. It provides an uncanny simulation of the famous Leslie effect or the classic swirls and swooshes inspired by the Phase 90. Control various settings with an expression pedal such as the GDVP5 Volume Pedal or an off-board switch such as the MXR Tap Tempo Switch . High-performance pitch shifting, fuzz and modulation in a ruggedly reliable housing. True hardwire bypass. Powered by 9 volt battery or supplied AC adaptor (ECB003).
