Markbass

collapse expand iconDescription

The Markbass Little Mark IV bass amp heads add some amazing features to the flagship Markbass Little Mark III amplifier, an industry standard for tone, portability and value. The bi-band limiter featured on this amp responds faster and more dynamically to your playing. It's paired with a 500-watt power amp providing impeccable bass frequency reproduction thanks to an MPT proprietary amp specifically designed for bass. In addition, the Little Mark IV includes a mute switch and the 3-way switch with Flat, Scooped or FSW (footswitchable) options.

Updated 4-Band EQ, Old School Filter, 3-Way Switch

An 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 four 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.

Bi-Band Limiter

The 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 the Little Mark IV amp head a great choice for anyone who enjoys a quick, punchy attack at high volumes.

Mute/Line Out Level Control/Pre-Post EQ Switch

Featured on the front panel of the Little Mark IV series amps are a convenient mute switch, along with 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, which allows you to set the XLR output's routing to before or after your EQ as required.

    I love the mark bass equipment I have. I have a 112 combo amp and 102p for at least 15 years. Never a problem. I bought this amp November 28 2024. Its been to the shop for warranty repair 2 times and as of today its going back again. And it was just returned 3 days ago from warranty. Warranty repair is in California and they don't cover shipping.

  • Great amp

    I bought this amp to replace a Markbass F1 that I used as my primary amp for many years. I've had the Little Mark IV for a month now and am very pleased with the tone, power and portability. I pair it with one or two 2x10 Markbass cabs depending on the gig. It sounds great and has plenty of headroom.

  • A great sounding amp head

    I bought this light weight amp head on the recommendation from some friends of mind in the music business, i was tired of carrying my old heavy Gallien Krueger RB 1000 amp head , could not believe the sound coming from it with my Peavey BWX cabinet with a 15 in Blk Widow speaker.

    This is the first bass amp head I've ever bought. However, I've played on several, and I've been playing for a while so I've seen some great heads. This one was amazing, above all the rest! Paired with a Schroeder 2x12 cab, this head gives me all the power I need. At half volume, I overpower the loudest band I play in. Definitely a great investment for someone looking to upgrade their amplification setup.
