500 Watts of Gig-ready Markbass Firepower

The Markbass Little Mark 58R’s superb size-to-power ratio makes for a compact and sonically flexible solution for all your gigging and recording requirements. This muscular 500-watt bass head delivers Markbass’s legendary, rafter-shaking thump from an ultra-light, mini-size enclosure. Gain, 4-band EQ, and Master volume controls offer straightforward tone-shaping, bolstered by an Old School filter and a 3‑way. Flat/Scooped/Footswitchable (FSW) switch for dialing in your overall sonic character. Additionally, the Little Mark 58R features a fast-response bi-band limiter, providing greater dynamic control and natural-sounding high‑frequency clarity — even when you crank it to the max. You also get a Mute switch, along with a Line Out level control, joined by Pre EQ/Post EQ and Ground Lift switches. Beyond that, this amp’s minuscule footprint ensures that you’ll always find room — even on the most space-challenged rigs. All told, the Markbass Little Mark 58R delivers stage‑ready power and sonic versatility in a pint-sized head that tackles the most demanding live gigs with supreme assurance.

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.

Ample I/O for the stage and studio

The Markbass Little Mark 58R's robust I/O section stands at the ready to take on any gigging or recording application with plug-and-play simplicity. Perfect for bassists with a sprawling stompbox collection, this head’s front-mounted effects loop optimally integrates all your favorite pedals. Next, you get an XLR Line Out with a transformer-equipped design to fight off any distortion or unwanted noise introduced by extreme transients. And when it's time to plug into your favorite cab, the Markbass Little Mark 58R's speaker output section boasts a heavy-duty speakON jack for a lock-tight connection.

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.”

Love it
Has everything most bass players would need. Sounds great, good eq, looks killer. Love it with my matching cab. Also, Dan R. at Sweetwater is the man!
Mark Bass Little Mark 58R bass amp and Mark Bass 58R 4x10 4 ohm cabinet

I am so excited to see that Sweetwater is offering the Mark Bass line because this the BEST bass rig I have used in 56 years of playing bass in many different bands. The sound is everything that was in my head but hard to obtain in a live setting. The amp is very easy to work with to get your tone. The amp and cabinet combination project evenly across the venue with the sound quality the same where ever you listen to it from...., and they're so light it makes an old man like me feel young again!!!

Music background: I play manby instruments but play bass and sing semiprofessionally in two blues bands.
