Core Advantages: Unrivaled Control and Hybrid Power
The 300W bass head combines the best of analog warmth with solid-state precision features.
Hybrid Power and Classic Warmth
- Variable Valve Drive Plus: At the heart of this bass amp head lies a 12AX7 tube preamp. The foot-switchable Variable Valve Drive Plus allows you to dial in rich, harmonically complex overdrive—from subtle warmth to full-blown grit—and blend it with your clean signal.
- Serious Output: Delivering 300 watts of high-quality power, this 300 Watt bass amp head can handle minimum 4-ohm loads, giving you flexible pairing options for single or dual cabinets.
- UK Engineered Excellence: The Ashdown ABM head is proudly designed in the UK, and built to the highest level of craftsmanship and component quality for maximum reliability.
Surgical Tone Shaping and Dynamics
- 9-Band Precision EQ: Go far beyond basic tone controls. This 300W bass head features a comprehensive 9-band EQ (3 rotary knobs plus 6 sliders) for detailed frequency sculpting, essential for eliminating room noise and ensuring your bass sits perfectly in the mix.
- Integrated Compressor: The renowned Ashdown One Knob Compressor keeps your dynamic range tight, powerful, and consistent at high volumes without coloring your fundamental tone.
- Sub-Harmonic Generator: Engage this feature to add a focused, octave-lower layer to your sound, perfect for adding unrivaled subterranean depth to the low end. This is a trademark Ashdown feature, controllable via footswitch.
- Visual Feedback: The iconic, illuminated VU Meter allows for precise and rapid gain-staging, ensuring you always hit the sweet spot for maximum tonal output.
Professional Connectivity
The Ashdown ABM head is fully equipped to integrate into any professional rig:
- Road-Ready Outputs: Features dual Neutrik Jack/Speakon outputs for reliable and flexible cabinet connections.
- Direct Signal Integrity: Includes a high-quality DI Output (balanced) for feeding a clean, isolated signal to the FOH or recording desk.
