Pre-Owned MXR M281 Thump Bass Preamp

The MXR M281 Thump Bass Preamp: Punchy Low-End with Studio-Grade Flexibility

Designed for the Demands of Modern Bassists

The MXR M281 Thump Bass Preamp delivers serious tonal flexibility in a compact, pedalboard-friendly package. Built around the preamp section of the revered MXR Bass DI+, this pedal is tailored to sculpt low-end with both power and precision. It’s a dynamic tool for bassists who need studio-grade control without lugging rack gear to every gig. Whether you’re after a subtle clean boost or full-on tonal reshaping, the Thump has the goods.

Parametric EQ Precision in a Stompbox

A semi-parametric 3-band EQ with sweepable midrange, gives you pinpoint control over your frequency spectrum. Dial in warm, round lows, punchy mids, or articulate highs, or completely re-voice your tone to fit any genre or mix. The Low and High controls offer fixed-frequency sculpting, while the Mid control provides adjustable frequency selection and cut/boost, empowering you to address trouble spots or enhance your sweet spots with ease.

Boost and Buffer with a Transparent Touch

The M281 isn’t just about tone shaping. With its wide-ranging gain control, it functions as a pristine clean boost or a subtle tone enhancer. Its buffered bypass ensures signal integrity from your bass to your amp or recording interface, making it equally suitable for live performance and studio setups. Whether you’re driving long cable runs or compensating for pedalboard losses, the Thump keeps your tone intact.

Roadworthy Design with Subtle Wear

This pre-owned unit is in great working condition, showing only light surface wear on the left and right sides as well as the bottom of the pedal. It’s purely cosmetic and doesn’t affect the performance in any way. No accessories or power supply are included, but the M281’s standard 9V operation ensures compatibility with most pedalboard power setups.

Built for Tone Chasers, Not Just Traditionalists

Bassists pushing boundaries or holding down the groove will find the Thump Bass Preamp to be a crucial tool. From vintage thud to hi-fi slap, it meets the moment with tonal flexibility and zero nonsense. If you’re looking to enhance your low-end presence without overwhelming your signal chain, the MXR M281 is your ticket.
