Thump Bass Preamp

M281

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. 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.
