With two flexible EQ sections, this amp offers complete tonal control. EQ1 features a five-band equaliser, allowing precision shaping from ultra-low bass to crisp highs. EQ2 incorporates the Old School and Millerizer filters, delivering everything from vintage warmth to Marcus Miller's signature slap tone. Both EQ sections are footswitchable, along with a mute function, making it easy to switch tones on the fly. The Mark Proprietary Technology (MPT) power amp ensures that the amp delivers pure, uncoloured bass tone, specifically designed to enhance the natural sound of any instrument.

Our team at Derringers has a soft spot for this little powerhouse. Its compact size and lightweight design make it a breeze to transport, and the tonal versatility is simply unmatched. It's like having Marcus Miller himself in your gig bag, minus the autograph requests.
