The SILK DRIVE pedal gives you the sound of a legendary boutique amp. It covers the range from warm cleans to bluesy overdriven tones, and perfectly expresses the subtle nuances of your picking. Equipped with Nutube, VALVENERGY pedals provide the response and harmonic distortion of a tube amp. Connection Mode can be switched according to your use: STANDARD (the pedal outputs an instrument-level signal), PREAMP (the pedal outputs a line-level signal) and CAB-SIM (the pedal outputs a line-level signal with an analogue cabinet simulator). Channel Switch function allows operation similar to a multi-channel amp when multiple VALVENERGY series units are connected, while an OLED display provides a visual indication of the sound. Buffered bypass reduces noise when the effect is turned off, and all-analogue circuits with the 9V power supply voltage boosted to 15V internally giving greater volume and headroom.
