MXR - JD-M281

Description

This pedal combines the tone-sweetening magic of the Echoplex® Preamp with a three-band EQ and midrange frequency adjustment so that you can dial in the perfect bass tone to punch up a solo, boost your signal in a live mix, sculpt more edge into the sound of a passive bass, and more.

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 Dunlop's 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 8 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.
