The MXR Thump Bass Preamp is a tone-sweetening,signal-boosting, and altogether groove-enhancing machine. This pedal wasconceived when the MXR design team and our in-house bass playersdiscovered that the Echoplex® Preamp’s sonic secret sauce made for justas delectable a pairing with bass as it does with guitar. Using thatcircuitry as a foundation, the MXR team added a simple yet potenttone-shaping interface so that you can dial in the perfect bass soundfor the stage and the studio.Crafting the sound you need is easy.
The Echoplex Preamp circuit conditions your signal with a carefullybalanced EQ profile, and this pedal’s tone controls let you take it fromthere. The Treble and Bass knobs cut or boost frequencies at 8 kHz and40 Hz respectively, while the Mid knob cuts or boosts the midrange asset by the Frequency knob, from 250 Hz to 1 kHz. This range offrequencies was selected to give players maximum flexibility and minimalfuss when refining their bass signal.
Whether you need to punchup a solo, boost your signal in a live mix, or sculpt more edge into thesound of a passive bass, the Thump Bass Preamp packs incredibleversatility into an MXR mini housing.
