Named after VOX's first amplifier tremolo circuit, the VIBRAVOX essentially recreates the unique and immensely satisfying Vib/Trem sound from a traditional AC30 and puts it into a pedal that can be used with any amp.To increase flexibility we've added additional user control and features. By including two Speed controls and an effects assign switch (T1/T2, T1/V2, V1/V2), a number of possibilities become available. The VIBRAVOX can be configured as a tremolo only or vibrato only pedal with two foot-switchable speeds. You can also choose to configure the pedal to switch between tremolo and vibrato. To top it off, the pedal automatically ramps between speeds, adding a taste of that unmistakable rotating-speaker sound.
