The Mesa Subway D-350 is the ultra-compact champ in MESA’s Subway Bass Series and, at only 3 pounds 2 ounces, represents the smallest, lightest bass amp in MESA history! While ultra-portable, it still packs a powerful punch with 350 watts of Class D power – All from a simple, intuitive feature set that provides all the tone-shaping tools you need and nothing you don’t to deliver the tone, feel, and response that has made the Subway Series our most popular to date.
