Weight: 40lbs Description Product Description Vintage takes flight with this breakthrough new instrument that combines the warm, organic quality of a genuine vintage amp with the huge, 3-dimensional sound of a modern, high-end amp. For those familiar with Tone King models, the Sky King combines the chunky, old-school vibe and touch-responsive feel of the Falcon with the voicings, flexibility, wide tonal options and features of the Imperial - all in a larger format for a bigger sound. A pentode/triode switch gives you the option of a crisp, present sound with a fast attack, or burnished, bell-like tones with depth and resonance. Fully hand wired, which extends the sound into a new dimension. Mark's hand wiring scheme gives this amp an especially intimate, tactile feel. Built-in Ironman attenuator adds tremendous functionality and value - and the Ironman in the Sky King has dual attenuation controls (lead and rhythm) to perfectly meet your needs.
