Description Product Description Meet a limited edition tribute to the 20 year-old vintage tone classic that started it all for amp master builder Mark Bartel and the Tone King brand. Builds on the Imperial's magic tonal recipe with hand wiring and a built-in Ironman attenuator (6 levels of attenuation, from 0db-36db) . No tweaks to the main signal path, but you'll find the reverb especially spacious and the trem especially smooth. The Ironman makes this the ultimate home or club amp. Loaded with the new Celestion G12M65 Creamback speaker. Rhythm Channel : The rhythm channel really delivers the classic blackface sound, instantly reconizable to fans of the Princeton or Deluxe Reverb, but with a more organic feel, like a really good vintage tweed deluxe. Lead Channel : The unique and effective Mid-Bite control makes the Lead Channel a lot more versatile than you would expect from a channel with only 3 controls. The Mid-Bite control is an exclusive Tone King design feature which does a lot more than simply adjust the midrange level - it completely transforms the overdrive character. When played clean, the woody resonance of the cabinet, liveliness of the 5AR4 tube rectifer, and the expressive dynamic response of the cathode-biased output stage work together to give you the raw midrange, silky top end, and loose feel of a genuine well-worn tweed deluxe - perfect for honky tonk or blues rhythm playing with a tele. Reverb : The Imperial's reverb circuit uses the same 12AT7 driver tube, 12AX7 receiver tube, and long-format 2-spring pan as those classic amps from the 1960s, to give you that same authentic spring reverb sound. Tremolo : The Imperial uses a vintage tremolo circuit which creates the tremolo effect by modulating the bias current of the output tubes. Compared to other methods (e.g. the opto-coupler method used in the Fender "blackface" era amps), this method creates the most gradual, smoothest, and roundest tremolo effect.
