The MXR Thump Bass Preamp offers all the features to offer a classic always-on pedal for modern bass setups. The idea for the pedal came about by chance when the MXR design team discovered that the Echoplex preamp also works wonderfully with electric basses. Based on this circuit, an effective EQ section has been added to the pedal, which can perfectly adapt the bass sound to the requirements on stage or in the studio. The treble and bass controls work as a cut or boost at 4 kHz and 40 Hz, the mid control also as a cut or boost between 250 Hz and 1 kHz. The frequency of the mid controller can be freely adjusted using the frequency controller. Regardless of whether you are looking for a bit of punch for emphasized solos, want to assert yourself better in the mix on stage, just want to boost the signal or give the sound of a passive bass more contour and character - the MXR Thump Bass Preamp offers musicians incredible possibilities in one compact unit MXR mini case.
