The Ashdown Rootmaster RM-500-EVO III is your all-in-one solution for powerful, versatile bass tones. This compact yet mighty amp head packs 500W of punch, equipped with a 5-band EQ, Sub Harmonic Generator, Compression control and Valve Emulated overdrive to shape your sound. With innovative features like the Analog Cab Sim Di output, you can plug directly into house PAs or recording interfaces for refined tone in any setting.

Shape Your Signature Sound

The Rootmaster RM-500-EVO III gives you an array of tone-sculpting tools to craft your distinct bass voice. The 5-band EQ provides precise control over lows, low-mids, mids, high-mids and highs. Engage the Sub Harmonic Generator to boost frequencies below 40Hz for thunderous low end. The Compression knob smooths out volume spikes for consistent dynamics. And the Valve Emulated overdrive adds warmth and grit. With this amp, you have the flexibility to fine-tune your tone for any genre or performance.

Direct and Powerful

While the Rootmaster RM-500-EVO III packs 500W of power, it also offers direct connectivity for recording or live playing. The Analog Cab Sim Di output emulates the sound of an ABM 8x10 cabinet, allowing you to plug directly into a mixing console. A balanced D.I. output also provides a post-EQ and post-effects signal for going direct. With the same tone-shaping controls as the standard output, you have full command over your direct signal.

Variable Valve Emulation and Dynamics Control

Add tube-like warmth and overdrive to your sound with the Valve Emulation control. This provides smooth, analog breakup at higher settings for a vintage vibe. The Compression knob allows tightening up dynamics or smoothing them out. Use it to even out volume changes for consistent levels or create punchier dynamics.

Direct Recording and PA Ready

The innovative Analog Cab Sim Di output offers options for going direct into recording interfaces, mixing boards and PAs. It provides emulations of Ashdown's acclaimed ABM speaker cabinets for dialing in classic Ashdown tones. The balanced D.I. output delivers your full, post-EQ signal for plugging into front-of-house systems. Use them together or individually based on your needs.

Road-Ready and Responsibly Built

Ashdown designed this amp for demanding tour schedules and environmental sustainability. It's housed in a rugged yet lightweight cabinet ready for transport in even the most cramped vans. What's more, Ashdown's commitment to repairability means this amp is supported with replacement components for over 15 years. By facilitating repairs rather than replacements, Ashdown minimizes waste for a greener footprint. For the gigging bassist, the Rootmaster RM-500-EVO III offers a perfect fusion of tone, functionality and eco-conscious design.
