Alchemist™ spins the visions of discerning guitarists into gold. Boasting sparkling, articulate cleans, touch-sensitive leads and a bright and colorful crunch, the all-tube Alchemist is a modern take on vintage amp design. Its remarkable tonality it owes to a 6L6 class-AB power section, featuring five 12AX7 preamp tubes and premium Celestion® speakers. Its timeless appeal, though, it owes to classic innovation, modern ingenuity and its namesake, an entrancing ancient mysticism. Alchemist exhibits a two-channel design, each channel with its own voice and identity. Beginning clean and fast, featuring an open top-end and tight bottom-end, Channel 1 opens gradually to present simmering blues tones that churn like spirits in a cauldron. Advancing toward saturation, Crunch mode turns up the heat adding the perfect touch of nastiness with added pick response and increased tonal complexity. Channel 2, achieving critical mass, invokes the famous white-hot Bogner gain—creamy, modern and screaming with sustain—offering everything from Brit rock right through to modern metal. Plus, with variable Bright settings, each channel can be customized to match the tone of your guitar and rig. Featuring a selectable power section, from 40 to 20 watts, the Alchemist sonority quickly transforms to display a very different kind of magic. When switched to 20 watts, Alchemist undergoes a complete sonic metamorphosis, changing its harmonic complexity and feel to conjure the essence of the legendary Brown sound. Reverb and Delay, in variable styles and levels, run in parallel separate from the original signal. The result is a rich, living and breathing, fully realized resonance capable of producing a complete tonal landscape. Alchemist also includes a four-button footswitch and a parallel effects loop.
