The new Little Mark IV amps add some amazing features to our flagship Markbass Little Mark III amplifier, an industry standard for tone, portability and value. This 300W version is a smart choice for those who don't need the full power of a 500W head. It offers new features such as the new bi-band limiter that responds faster and more dynamically to your playing, a mute switch, and a 3 way rotary-switch that includes the options of a Flat, Scooped or FSW (Footswitchable) EQ options. In addition, this new amp head can be powered using multivoltage sources from 120V to 240V so it's possible to bring and use it almost everywhere in the world without needing external converters.

Little Mark’s legacy

Since our beginning 20 years ago, Markbass pioneered small amp design with its "Little Mark" series creating an industry standard thanks to their amp's compact size, light weight, along with its signature warm and natural sound. That legacy has been preserved with the Little Mark IV and has evolved to include the addition of new features requested by many of our artists and customers.

Updated 4 band EQ, Old School filter, 3 way switch

Our updated 4 band EQ section features very effective controls allowing you to easily find the sound you want, boosting or cutting up to 16dB for each of the 4 bands to cover all the tonal nuances needed in any genre of music. Additionally the Old School filter cuts your high frequencies and gives a round and smooth tone. The 3 way rotary-switch allows you to choose between a super-balanced flat tone, a scooped preset that drops the mids while boosting the lows and highs - giving a superb slap sound, or lastly the 'FSW' option to control both mute and the Scooped EQ on demand by connecting an optional dual footswitch.


The Little Mark IV features a multivoltage power supply that accepts inputs from 120v to 240v so you can use it in countries with different voltages without having to carry an external converter (not available in the 100V version manufactured for Japan).

Bi-band limiter

Our new bi-band limiter responds faster and more dynamically to your playing than traditional limiters do and lets your high end "breathe" for a more natural sound. It makes our amp heads the best choice for anyone who enjoys a quick, punchy attack at high volumes.


Featured on the front panel of the Little Mark IV series amps are a handy mute switch, and the Line Out level control knob that allows for precise control of the signal sent to the mixer/PA. On the rear panel is a Pre-Post EQ switch allowing you to set the XLR output's routing to before, or after your EQ as needed.


Many other bass amps on the market use power amps that are not specifically designed for bass. At Markbass, Marco De Virgiliis invested heavily in R&D to develop proprietary power amp technology in house. Our MPT power amp was built from the ground up to respect and elevate the inherent tone of your instrument.
