2023 Mesa/Boogie Subway D-350 Ultra-Compact 350-Watt Bass Amp Head w/ Bag

This Subway D-350 is in excellent condition — about as close to new as a used amp gets. The textured black chassis is clean all around with no scratches, scuffs, or marks worth mentioning. All knobs, switches, and indicator LEDs are in perfect working order, and the rear panel connections are clean and undamaged. Rubber feet are all intact. No modifications, no repairs — completely stock. Tested and functioning perfectly.

Includes the original Mesa/Boogie padded gig bag with shoulder strap (showing some minor surface dirt on the front pocket, but fully intact and functional) and the AC power cable. Weighs in at right around 3 lbs.

From Mesa/Boogie:

The Subway D-350 is the ultra-compact entry in Mesa's Subway Bass Series — their smallest and lightest bass amp ever, built on the foundation of the acclaimed Subway D-800. A solid-state preamp paired with a Class D power amp and switch-mode power supply delivers 350 watts into 4 ohms in a package that weighs just over three pounds and fits in the accessory pocket of a gig bag. Made in Petaluma, California.

The D-350 covers a lot of ground for a micro head. The Variable Voicing control sweeps the amp's response from flat to a vintage-style scoop, reshaping frequency response across multiple regions with a single knob. The fully active 4-band Baxandall EQ (Bass, Low Mid, High Mid, Treble) gives precise tonal control, and the Bright switch adds top-end clarity when you want it. Separate Gain and Master Volume controls let you dial in everything from clean and articulate to mild overdrive, with a built-in fixed high-pass filter keeping sub-sonic mud out of the picture.

It handles active and passive basses equally well via a front-panel switch, and the Input Mute lets you tune silently. The rear panel is fully loaded for its size: balanced XLR direct output with pre/post EQ, mic/line level, and ground lift switches; headphone output for silent practice (no cab load required); aux input for playing along with media; USB power port; and dual Speakon speaker outputs. No cooling fan — completely silent operation.
