Ashdown Bass Tone Just Got Better
Ashdown kicks it up a notch with the ABM 300 EVO IV bass head. Boasting a stage-rumbling 300 watts of output, a tube-driven preamp section, an extended 9-band EQ, and tons of tone-shaping flexibility, the ABM 300 EVO IV is another incarnation of the ABM line of Ashdown amps — the same series that professional bassists rely on to deliver their tone to the masses on stages around the world. Put the power, versatility, and tone of an Ashdown amp to work in your own bass rig, with the ABM 300 EVO IV.
New features extend your tone-shaping flexibility
The new preamp section in the ABM 300 EVO IV features variable drive technology. A dedicated drive knob lets you adjust the amount of current flowing into the 12AX7 tube for tones that range from the cleanest of cleans to the fattest of overdriven thumps. The updated 9-band EQ section will surprise even dedicated ABM players, with tight tonal control including knobs to handle bass, middle, and treble and an expanded 6-band graphic for fine-tuning. Ashdown's familiar 1-knob compressor and subharmonic generator work to make your tone tighter and fuller than you've ever heard it before and help you claim your rightful place in any mix. All the while you can keep an eye on your levels with the iconic Ashdown VU meter situated right on the face of your amp. Add all of this tonal control the flexibility of footswitching — the EQ, compression, subharmonics, even the variable drive can all be kicked in and out with a tap of your toe.
