And that makes Hughes & Kettner Coreblade amplifier the top-notch tube amp of choice for modern metal axe-slingers.An Amp Head with Wicked ToneTwo of the four channels are voiced to offer completely different high-gain alternatives. Beyond that, the amp head sports a phenomenally versatile Drive channel and a Clean channel offering oodles of headroom. Boost is separately switchable, and three effect modules may be used simultaneously for each per channel. The ultra precise, remarkably musical Intelligent Dual Breakpoint (IDB) noise gate (which simultaneously measures the gain at the input jack and after the preamp, to react perfectly in any given situation) is available for all channels. The power amp feedback circuit reconfigures to tap the full sonic potential of each channel, evoking sounds that do everything from sparkle and chime, to sing and scream. With jackhammer riffs, full-blown metal madness and more, this Hughes & Kettner tube amp head gives you wicked tone galore. No compromises in tone controlProgrammable and maintenance-free PRN (Programmable Resistor Network) potentiometers are the most sophisticated analog sound-shaping tools. Only Hughes & Kettner has mastered the science of these elaborate knobs to benefit your art. Engineered to deliver a lifetime of service without ever becoming scratchy, these knobs let you tweak each of the four channels fully independently. No two channels share even a single knob. All Gain, EQ, Presence, Resonance, and similar settings may be stored in 128 presets and retrieved with a simple toe-tap. Best of all, every sound is purely tube-powered-no modeling here.
