Features: Combined effect pedal with 6 effects, including delay, chorus, distortion, overdrive, booster, buffer. With true bypass to eliminate any signal interference when all are off. Delay - Natural sounding delay with the analog direct signal path and supports controls for dry/wet signal ratio (Level), delay feedback (Repeat), and delay time (Delay). Chorus-- Premium all-analog circuitry with bucket-brigade line. Rate and Depth knobs provide fine sound adjustment, creating some fresh and comprehensive reverb effects. Distortion-- Based on MXR distortion, the distortion pedal gives you magical classic distortion tones and supports controls for output volume (Level) and distortion amount (Distortion). Overdrive-- Gives you access to warm and amp-like overdrive that is touch-sensitive and supports controls for output volume (Vol), frequency (Tone), and overdrive amount (Drive). Buffer & Booster-- Knob=0: pure buffer, Knob>0: pure boost. The buffer is an active electronic circuit that keeps your guitar signal strong and preserves the frequencies of your guitar sound. The buffer booster offers excellent, stable buffering and a fantastic clean boost.
