The Tube Drive is simple to use and flexible enough to authentically reproduce a wide pallette of tones from mellow blues, to classic rock overdrive and smooth, fine-grained, supersaturated modern guitar tones. The secret is Three dual triode tubes biased to produce extremely symmetrical signal clipping across 6 cascaded gain stages. In practice this means the pedal responds empathically to pick attack with a smooth and graceful breakup characteristic on low drive settings, producing an expressive warm blues tone. Increasing the drive introduces rich and musical harmonic overtones that pack serious punch for a larger-than-life, “hot-rodded” amp tone. The tone quality of the Tube Drive exceptionally musical, organic and sounds distinctly different to pushing an amp with a solid-state diode clipping or even hybrid opamp/tube overdrive pedal and it won’t mask the natural sound of your guitar and amplifier.

All Tube gain circuitry: The Tube Drive is the only pedal you can buy that has a complete tube guitar preamp inside – 100% analog, class-A, all-tube means no silicon in the signal path. This topology gives the Tube Drive fine control over a wide range of gain characteristics from mild breakup to creamy saturation. Tube swapping: The tone and gain characteristics of the Tube Drive can be drastically altered by interchanging tubes – in fact the pedal is designed for easy access to the tubes for this purpose. It can be quickly and easily transformed into a hi-gain distortion beast, mellow blues driver or boost pedal by simply removing a tube and replacing it with a different type. Bax-Stack “active” tube tone control: The Tube Drive is the only overdrive with an active tube tone control. The Bax-Stack is a real treble boost (and cut) circuit with zero insertion loss, unlike passive tone stacks which can only remove frequency content (“tone-sucking”). The tone range is optimised to work over important frequencies essential for mellow jazz tones to some serious crunch. Low-end coutour switch: Active low boost for a warmer, richer sound. Especially useful with single coil pickups to thicken the sound or when playing at low volumes to compensate for loudness. Dakaware Knobs: Authentic phenolic Dakaware, Chicago knobs manufactured in the U.S.A using the original 1940s moulds! Daylight visible orange L.E.D.: Indicates when pedal is engaged. Includes 12V Wall-wart Power Supply: High quality low-noise switched mode 12VDC at 1.5A wall-wart compatible with all our pedals. Accepts 100V to 240VAC mains input and comes with different mains outlet adaptor plugs, so there is always a plug that fits the country that you are playing in. - See more at: http://www.effectrode.com/tube-drive/#sthash.aVKwMTDf.dpuf
