The MXR Thump Bass Preamp is a tone-sweetening, signal-boosting, and
altogether groove-enhancing machine. This pedal was conceived when the
MXR design team and our in-house bass players discovered that the
Echoplex® Preamp’s sonic secret sauce made for just as delectable a
pairing with bass as it does with guitar. Using that circuitry as a
foundation, the MXR team added a simple yet potent tone-shaping
interface so that you can dial in the perfect bass sound for the stage
and the studio.
Crafting the sound you need is easy. The Echoplex
Preamp circuit conditions your signal with a carefully balanced EQ
profile, and this pedal’s tone controls let you take it from there. The
Treble and Bass knobs cut or boost frequencies at 4 kHz and 40 Hz
respectively, while the Mid knob cuts or boosts the midrange as set by
the Frequency knob, from 250 Hz to 1 kHz. This range of frequencies was
selected to give players maximum flexibility and minimal fuss when
refining their bass signal.
Whether you need to punch up a solo,
boost your signal in a live mix, or sculpt more edge into the sound of a
passive bass, the Thump Bass Preamp packs incredible versatility into
an MXR mini housing.
