The all-analog base overdrive pedal 4 on the floor Classic Bass Overdrive (4-OTF-PEDAL) is an all-analog base overdrive pedal. Accurately emulates 4 kinds of overdrives found in classic vacuum tubular circuits, allowing you to control overdrive pass and clean blend with drive/gain, and high-pass/low pass filters. The result is a sound make-up that fits a wide range of music genres and play styles without compromising touch sensitivity and musical performance or emitting excess noise. The power supply is DC 9V to DC 18V with polarity auto-sensing capabilities, and it is compatible with almost all power supplies. The 4-OTF-PEDAL is also compatible with base amplifiers such as MAGELLAN 350 and MAGELLAN 800. ■ Reminiscent of the clean channels of the 4 drive select "GEAR" 1st vacuum tube amplifier, giving you an overdrive tone when driving hard. It emulates a mild overdrive tone of the 2nd tube amplifier with a small amount of compression. Natural feeling, touch-sensitive algorithm, has a very mild compression, the more you pick the stronger, the more texture you get. The overdrive has been shifted more aggressive than the 3rd 2nd GEAR. Larger compression for a tighter feel. 4th most aggressive gear Drives hard to enter distortion area. There are many horoscopic sounds and compression that do not affect the tone and feel of the base itself. ■Features: Lightweight aluminum chassis, robust stomp switch, low noise and silent switching circuit, 4-position overdrive "GEAR" selector switch, high pass/low pass filter (overdrive engine only), parallel clean signal pass, drive sensitivity switch (DRIVE SENSITIVITY)
