Tube Pilot gives you the sound and feel of playing an old tube preamp cranked up to natural distortion. Inside the effect is a 12AX7 tube, the same one used in the preamps of many classic guitar amps, creating the rich, harmonically saturated distortion that only an electron tube can provide. With the Tube Drive knob, you can control the operation of the lamp, from making your armpits sweat, to turning on the afterburner and blasting it into the atmosphere. The sound and feel you get with the Tube Pilot is like what you'd get from an old school tube amp - it's super sensitive and responsive to how you strike the strings. Just like with the lamp on, selecting the dynamics allows you to seamlessly transition from warm, clean chimes to thick blues or rock sounds full of sustain. All-analog circuitry ensures noise-free operation, while True Bypass circuitry ensures sound integrity when the effect is turned off. Everything is packed in a neat metal case that will easily withstand the rigors of rehearsals and concert tours. powered by a 12AX7 preamp tube fully analog circuitry warm, organic sounds true bypass connections mounted from the top of the unit compact metal housing Power consumption: 9V DC 300mA
