Flat 4 Booster
This vacuum tube booster can be used for a mid-boost, treble-boost, and overdrive, in addition to a full-range boost. Its Baxandall tone circuit allows adjustment from the flat position to the desired boost or cut range. Raising the gain will gradually apply a low-cut, giving you an overdrive sound that’s strongly reminiscent of sought-after vintage tones. An independent mid-boost switch lets you switch the response of the mid-range, which is ideal for playing lead. This is a great unit for blues guitarists who wish to highlight their picking nuances.
