Big Bass Authority in a Grab-and-go Head

Wherever you go, the Markbass Nano Mark II will deliver the company’s legendary, rafter-shaking thump. This 500-watt bass head begins with the brand’s custom-designed MPT (Mark Proprietary Technology) power section, voiced for high headroom and a pure, clear tone that enhances your instrument’s inherent character. Gain, 4-band EQ, and Master volume controls offer straightforward tone-shaping and efficient sonic sculpting. You also get a Line Out jack, joined by Pre EQ/Post EQ and Ground Lift switches. A high-quality effects loop is also on tap, making it easy to integrate your pedalboard. Lightweight and stage‑friendly, the Nano Mark II is ideal for gigging bassists who want portability without sacrificing authoritative tone or room-filling volume.

Custom-designed MPT power amp

To ensure optimal low-end performance, Markbass amplifiers come equipped with a proprietary MPT (Mark Proprietary Technology) power amp designed by the brand’s founder, Marco De Virgiliis. This high-headroom power amp was purpose-made to supply an authoritative output with sharp definition and a lively, dynamic feel. Above all else, the MPT is a testament to Markbass and Marco's uncompromising commitment to supplying professional musicians around the world with superior bass tone.

Markbass: over 20 years of Italian innovation

Founded by Marco De Virgiliis in 2001, Markbass has been a global leader in bass amplifiers and instruments for over 20 years. Built proudly in Italy, the company’s products span a diverse range, comprising compact yet powerful amplifier heads, all-in-one combo amps, and lightweight, durable speaker cabinets loaded with cutting-edge technology. Beyond that, many bassists here at Sweetwater are also ardent proponents of the brand’s pedals, basses, and guitars. Known for its pioneering use of neodymium magnets to reduce weight without sacrificing sound, Markbass remains focused on sonic clarity and tonal accuracy, crafting amplifiers that highlight the true voice of your instrument. Endorsed by renowned artists, such as Marcus Miller and Jeff Berlin, Markbass represents a family of brands driven by Italian passion, style, and craftsmanship, with continued praise from a wide array of musicians, such as Supertramp’s Cliff Hugo, who remarks, “You transfer the quality of your people into the products you make.”
