Unlock legendary MESA tone and massive flexibility in a compact, pedalboard-friendly footprint. Available now at Haggerty’s Music, the Mesa/Boogie Subway+ Bass DI-Preamp II combines the best elements of the acclaimed Subway amplifier series into an all-in-one tone shaping tool. Whether you are laying down tracks in the studio, practicing silently at home, or touring the world, this feature-rich DI-preamp delivers premium bass sound without the clutter.

Legendary MESA Heritage, Reimagined for Your Pedalboard

Building on the foundation of the world-class Subway® D-800™, D-800+, and D-350 amplifiers, this second-generation DI-preamp condenses premium MESA engineering into a chassis that is 35% smaller than its predecessors. This is the ultimate "amp-in-a-box" and a reliable micro-sized backup rig that slides easily into your gig bag.

Powerful Tone Shaping Without the Complexity

Designed to easily adapt to both active and passive basses, the Subway+ Bass DI-Preamp II features an extended-range J-FET preamp circuit. Craft your signature sound using the intuitive variable Voicing control—shifting smoothly from a flat, modern response to a warm, vintage scoop.

Take surgical control over your mix with a fully active 4-band Baxandall EQ, featuring sweepable semi-parametric Low-Mid and High-Mid frequency bands. Block headroom-robbing sub-sonic rumble with the award-winning variable Hi-Pass Filter, or instantly inject punch using the dedicated Deep and Bright switches.

Versatile I/O for Studio, Stage, and Home

From the bedroom to the arena, the Subway+ II has your back:

  • Practice Anywhere: Plugin a media player via the Aux Input and practice silently using the dedicated Headphone output.
  • Pro Direct Out: Deliver iconic MESA tone straight to front-of-house or your recording interface via the studio-grade, balanced XLR Direct Output (complete with Pre/Post EQ and Ground Lift switches).
  • Flexible Routing: The 1/4" Preamp Output supports both unbalanced (TS) and fully balanced (TRS) lines, offering enough clean signal level to drive any pro-audio power amplifier.
