Seymour Duncan SFX-11 Twin Tube Blue Distortion Guitar Effects Pedal


The Seymour Duncan SFX-11 Twin Tube Blue is the stompbox for the no-compromise blues player seeking a range of bluesy tones from classic Chicago raunch to modern high-gain sounds.The Twin Tube Blue is a high-quality, 2-channel guitar preamp voiced especially for the blues—modern blues, Chicago blues, Texas blues, and classic rock. Unlike its Twin Tube brethren, the guitar pedal features a duet of premium, mil-spec, subminiature, USA-made Philips-Sylvania 6111 dual-triode tubes. These tubes are voiced similar to a familiar 12AU7.And the Twin Tube Blue distortion pedal will never degrade into "starved plate mode," where the tubes function like clipping diodes and do not actually amplify. The Twin Tube Blue's high-plate voltage and 100% vacuum tube signal path allows the tubes to operate at their fullest potential and provide maximum dynamic range. The means you get the most gain and all the smooth, bluesy tone you expect from a high-quality tube preamp. The SFX-11 Twin Tube Blue's 2 channels provide versatility. The Rhythm channel offers up sparkly chords and bright, punchy leads. The Lead channel starts with familiar Texas blues and goes all the way to the heaviest blues tones you'll ever need. The Twin Tube Blue is true-bypass and features a heavy-duty chassis and a fully encapsulated toroidal transformer for quiet operation.
