Available Soon Notify me

Full-featured Compact Bass Combo

Scores of discerning bass players rely on Ashdown amplifiers like the Rootmaster for reliable tone and rock-solid performance. This 500-watt bass combo packs a five-band EQ, overdrive, a subharmonic generator, and onboard compression into a compact ported cab with a powerful 15" speaker for endless tweaking and tonal flexibility for the stage and studio. The Rootmaster makes a great rig for gigging and practice: an XLR output lets you run straight out of the amp into a soundboard without a separate DI box, and a separate input with Line Mix level control lets you crank up backing tracks and jam along.

Ashdown Rootmaster 500-watt Bass Amplifier Combo at a Glance:
  • An EQ built for tone tweakers
  • One-knob overdrive, compression, and subharmonics to shape your sound
  • Ashdown delivers the modern bass sound
An EQ built for tone tweakers

Ashdown bass amplifiers are known for their flexible equalizers. The Rootmaster RMC115 has a five-band EQ specially voiced for bass guitar, with bands at 1.5kHz and 240Hz to tame growly mids and muddy low end, along with traditional bass, middle, and treble controls for broadband sculpting.

One-knob overdrive, compression, and subharmonics to shape your sound

A flexible EQ is only half of the tone-shaping power the Rootmaster has to offer. Live and studio musicians are sure to appreciate the simple one-knob compressor for adding extra punch and smoothing out leads. A flexible overdrive control lets you dirty up your sound with subtle grit to full-on fuzz. And for floor-shaking bass, you can dial in the Rootmaster's onboard subharmonics generator for an instant boost in low-end resonance.

Ashdown delivers the modern bass sound

With an artist roster that has included Adam Clayton of U2, James Jamerson Jr., and John Entwistle of The Who, Ashdown is responsible for shaping the sound of the modern bass. Ashdown amps serve up punchy dynamics with powerful, controlled lows and modern sheen. Sweetwater bassists like Ashdown amps for their durability to stand up to tour-grade abuse. Check out the Rootmaster for an amp with tones and features that won't let you down on the road or in the studio.
