The head - version of our popular combo amp Kleiner Muk. Compact, light, with powerful and assertive tone.

    To replace the power tubes if needed, you only have to remove the grid and replace the tubes. There is no other intervention necessary, the bias current is adjusted automatically by the circuit itself.

Due to its smart and stable construction, with these features Kleiner Muk sounds like a “big one” and outmatches even some of the more powerful combos.

Everything is possible, from mellow jazz tones with a strong bass or brilliant & twangy clean to fresh blues-crunch/overdrive to singing fat high-gain lead. All available via the footswitch (clean/drive/drive+boost).

Furthermore - thanks to its 4 switchable power levels - you can enjoy a rich tube sound full of overtones in any situation from bedroom level to club stage.

Or simply enjoy the different sound formations in the various power levels according to your own taste.

With a big cabinet you can reach enough volume even for a larger stage. Suitable cabinets are available from us. Of course, any other cabinets with 4, 8 or 16 ohm (total impedance) will work too.

Detailed features of Kleiner Muk:

Clean Channel

  • The Tone control influences the bass/treble ratio very efficiently and well-balanced.
  • The Bright switch brings more brilliance or more twang, depending on the position of the Volume control.
  • Depending on your sound-idea (really clean, twangy or slightly crunchy) you can virtually influence the gain via Volume control.
    And via Tone control (situated prior to the Volume in the circuitry) you can choose which frequencies are crunched more - e.g. basses less and treble more (this is recommended when Volume is wide-open or for guitars with strong bass).

Overdrive Channel

  • The Edge control works similar to the Tone control - full ccw means more mids and bass, full cw means more treble.
  • Boost switch (foot- switchable): This adds an additional tube stage, resulting in a richer distortion structure and producing a very creamy lead sound with high gain.
    For fat sounding guitars or pickups, resulting in a muddy tone at the lower or palm-muted strings, it is recommended to use the Tight switch.
  • Tight switch (to prevent a sludgy tone): Reduces the basses and some of the deep mids at the 1. tube-stage to create a tight tone and to avoid muddy sounds when with high gain (e.g. at high gain with the neck-humbucker on).

Global

  • The Smooth circuit (foot- switchable) creates a softer tone by slightly softening the presences. This can also be used to achieve more bite when switching from a more temperate rhythm play to solo play.
  • The serial effects loop is ready for every conceivable device. You can adjust the send level via potentiometer and the return gain can be set in two different levels.
  • Reverb circuit (foot- switchable) controls the TAD™ spring reverb.
  • 4 power levels are available via 2 switches:
    • Full / Half (center position = standby) switches the operating mode of the output tubes, reducing their power by 50%.
    • SE/PP: SE (single-ended) = Class-A (only one output tube is operating) / PP (push-pull) = Class-AB (both output tubes work).

Tubes

  • Preamp: 4x ECC83/12AX7 from Sovtek (V1, V2) & JJ (V3, V4). They are situated horizontally on the inside of the case.
  • Power amp: 2x 6V6GT from EH, TAD od. JJ, which are very stable in the basses and transparent in the highs. All Tubes can be replaced any time with no adjustments needed (Auto-Bias).

Speakers

  • You can use 1 or 2 cabinets with 16 ohms, 1 or 2 with 8 ohms or 1 with 4 ohms.
