Description:

Up for sale is a meticulously maintained Tone King Imperial Mk I in excellent condition. This is the original 20W, two-channel boutique masterpiece that put Tone King on the map, offering the perfect blend of 1950s "Tweed" grit and 1960s "Blackface" shimmering cleans. What sets this particular unit apart is the pro-level speaker upgrade. I have swapped the stock speaker for a Tone Tubby Red Alnico 12" Hemp Cone speaker (8-ohm). If you find typical ceramic speakers too "brittle," this hemp cone is the answer. It delivers a rich, full spectrum of tone with silky rolled-off highs and a rock-solid bottom end that never gets muddy.

Amp Features:

  • Two Channels: Rhythm channel for glassy, touch-sensitive cleans; Lead channel for warm, articulate crunch with a dedicated "Mid-Bite" control.
  • Tube-Driven Effects: Onboard spring reverb and bias-modulated tremolo for authentic vintage American tones.
  • All-Tube Signal Path: Powered by 2 x 6V6 power tubes and 12AX7 preamp tubes.

The Tone Tubby Red Alnico Advantage:

  • Organic Sound: The hemp fiber construction provides a sweeter, more natural sound than standard paper cones.
  • Alnico Compression: The Alnico magnet offers a smooth, lively compression that feels incredibly responsive to your playing dynamics.
  • High Headroom: Rated at 50W, this speaker provides ample clean headroom, allowing the amp's natural character to shine through without unwanted speaker breakup.

Condition:

  • Performance: This amp is in perfect working order and sounds incredible. The Tone Tubby upgrade takes the headroom and smoothness to a level the stock speaker simply can’t reach.
  • Aesthetics: Excellent condition with very minimal home-use wear. No structural issues, tears in the Tolex, or grill cloth snags.
  • Small Quirk: The jeweled power light is occasionally intermittent; it doesn’t always illuminate when the amp is powered on. This is a common minor cosmetic occurrence with these vintage-style assemblies and has zero impact on the amp's performance, tone, or reliability.

Included:

  • Tone King Imperial Mk I Combo Amp
  • Power Cable
  • Please note: The original footswitch is not included. The Mk I uses a standard 1/4" TRS dual-latching footswitch (readily available and inexpensive) to control the Channel and Tremolo functions.

Shipping: 

  • Professionally packed, insured and shipped via UPS to the Lower 48.
  • Local pickup available in the Seattle area, but willing to meet as far as 2 hours in any direction.
