MESA/Boogie today unveils the new Subway®+ Bass DI‑Preamp II, a compact, full‑featured follow‑up to its highly acclaimed first‑generation Subway bass preamp pedals. Consolidating the strengths of the original two preamp models into a single, streamlined unit, the Subway+ Bass DI‑Preamp II adds smart refinements that give bassists all the tone‑shaping tools they need to capture the sound, feel, and response that have made the Subway Series market leaders in premium bass tone. The new Subway+ Bass DI‑Preamp II is now available worldwide at authorized MESA/Boogie dealers, at Gibson Garage locations, and at www.mesaboogie.com. 

Building on the foundation laid by the celebrated Subway® D‑800™, Subway® D‑800+, and Subway® D‑350 preamps, the new model delivers world‑class MESA bass tone in a format that is approximately 40% smaller than previous Subway+ design. The result is a road‑ready, studio‑savvy preamp that’s equally at home on a tight pedalboard, a desktop, or riding along as a micro‑sized gig-bag solution.

Designed for power without complexity, the Subway+ Bass DI‑Preamp II features an extended‑range J‑FET preamp that plays beautifully with both active and passive instruments, plus an Input Mute footswitch for silent tuning. A Deep switch adds roundness and low‑end weight, while a Bright switch lends bite and top‑end sparkle. MESA’s award‑winning variable Hi‑Pass Filter (30 Hz–150 Hz) removes headroom‑robbing sub‑sonic content so players can precisely tune their low end to the musical style, ensemble, or venue.

Independent Gain, Boost (footswitchable with dedicated level control), and Master Volume controls unlock a wide palette—from warm, rounded cleans to mix-ready drive. The Variable Voicing control sweeps the overall character from a flatter, modern response to a more vintage-inspired contour by intelligently adjusting multiple frequency regions with a single knob. For deeper sculpting, a fully active 4-band Baxandall EQ provides ±12 dB of Bass, Low Mid, High Mid, and Treble, with sweepable Low-Mid (150 Hz–1.8 kHz) and High-Mid (300 Hz–5 kHz) frequency controls for surgical precision.

Flexible connectivity makes the Subway+ Bass DI Preamp II a natural fit for practice, stage, and studio. Aux In and Headphone Out allow players to blend a media source with their bass for quiet, on-the-go rehearsal. The Preamp Output supports ¼” (6.35 mm) TS unbalanced or ¼” (6.35 mm) TRS fully balanced connections and delivers ample level to drive any pro audio power amp. A mic-level balanced XLR DI with Pre/Post EQ and Ground Lift routes iconic MESA tone directly to front-of-house, monitors, or recording interfaces with ease.

With its ideal mix of compact size—just 2.25” (57 mm) H × 6” (152 mm) W × 4.25” (108 mm) D—light weight, 9–18 VDC (either polarity) power flexibility, and stellar tonal control, the Subway+ Bass DI‑Preamp II is a powerful solution for silent or live practice, studio sessions, and touring. Whether feeding PA and/or backline in small to midsize venues or standing by as a trusted emergency rig, it brings unmistakable MESA authority to any bass setup.
