SFX-11 Twin Tube Blue - Too often, inexpensive tube gear runs in "starved plate mode," where the tubes are not actually helping to create the distortion. 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. This means you get the most gain and all the smooth tone you expect from a high-quality tube preamp. Two channels, with individual volume and gain controls provide a ton of versatility. Like all Seymour Duncan pedals, the Twin Tube Blue is true bypass and features a heavy duty steel chassis.
