Rhythm Channel

The rhythm channel starts with a classic "blackface" era tonal voicing, familiar to fans of the late 60's Deluxe Reverb or Super Reverb. It gives you the shimmery clean tones and gritty, ringing overdrive that this style of amp is known for, but with a vivid clarity and lush depth which brings out all the harmonics and overtones in your guitar's sound. A three-position "bright" switch allows you to tailor the response for just the right amount of shimmer in the top end.

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.

With Mid-Bite fully off, the Lead Channel reacts much like a tweed amp. When played clean, the woody resonance of the cabinet, liveliness of the 5AR4 tube rectifer, and the expressive response of the cathode-biased output stage work together to give you the raw midrange, silky top end, and soft compression that define the vintage tweed sound - perfect for honky tonk or blues rhythm playing with a tele.

As you dig in harder, you'll feel the sweet, round top end begin to develop a stinging bite. Crank it up into the distortion zone, and the tone gets even fatter and thicker. Compression from the cathode-biased output stage softens the pick attack as single notes and chords swell and sustain in endlessly evolving shades of thick, meaty grind.

As you turn up the Mid-Bite control, a midrange peak appears while the bottom end is simultaneously tightened up, which transforms the tone into more of an English-style crunch. The amp develops a tighter feel as single notes really start to sing and sustain, and chords become chunky with a rich array of overtones.

Reverb

The Meteor/II includes a reverb circuit which is inspired by the classic standalone reverb units of the 1960s. This circuit has its own 12AX7 tube preamp and 6V6 tube driver, driving a full-size 3-spring pan.
A 12AX7 tube driven reverb receiver allows for shaping the sound of the reverb signal with its own reverb tone control, and for controlling the reverb level for each preamp channel individually, via the back-panel mix controls for the lead and rhythm channels.

The "dwell" control, located on the front panel, controls the signal level of the reverb driver, and gives you even more control over the reverb sound. At lower settings, you'll get a lush sound which is more like a vintage plate reverb sound. At higher settings, you'll get an over-the-top splashy, drippy surf sound.

With the dwell, tone, and mix controls, you have the ultimate flexibility to dial in your own perfect reverb sound.

Tremolo
The Meteor/II uses a vintage 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 a smooth, gradual, and rounded tremolo effect.

The tremolo effect can be turned on and off via the footswitch.

Bias Adjustment
Although the output tubes of the Meteor/II are primarily cathode-biased, bias adjustment controls are provided for precisely setting the bias current of each output tube. Bias current is measured by attaching an external ammeter to a set of test jacks, and activating the each tube, in turn, with a bias activation switch (shown at left). Bias current is set by adjusting a 20-turn trimmer pot with a small screwdriver. The entire biasing procedure can be performed in less than 5 minutes, and does not require disassembly of the amp.

Speaker
The speaker used in the Meteor/II is the hemp cone model #1891. This speaker was designed in collaboration with Eminence Speaker Corp. It is a unique speaker, and is unlike any of the standard Eminence models. It combines the sweet, articulate top end of an alnico speaker with the percussive power and warmth of a ceramic magnet speaker. It has a rich, balanced tone which manages to deliver both exceptional clarity and a sweet, musical top end.

Models
Amplifier Model Selection
The Meteor/II is available in 4 different output power levels, each with a different selection of output tubes. The 6V6-based models (model 720 and 740) are greatly preferred by the designer, as these define the classic Tone King sound as described above. The EL-84 based models (model 715 and 730) offer the unique sonic characteristics of EL-84 output tubes, which have a slightly thinner bottom end, a more prominent midrange, and a more compressed dynamic response. When driven into distortion, EL-84s cannot create a tweed-like overdrive, regardless of the setting of the Mid-Bite control, but instead develop a crunchy growl, which is unique to this tube.

Extension Cabinet Selection
A variety of extension cabinets are offered, which feature the same design construction as the combo cabinets. Both 1x12 and 2x12 cabinets offer the option of a straight front or slanted front. A slanted front cabinet is to be used with an amplifier head, as the depth of the top matches the depth of the head cabinet. A straight front cabinet is to be used when either a combo or another extension cabinet is to be set on top of it.
