Small, evil, patient, suddenly alive – it strikes when you do. Same power and feel as a real valve amp, without the glass, heat or weight. Touch the strings and it breathes. Stop – and the snake waits, coiled and ready. It follows you – the Master!

HIGH Voltage, Real Feel

Magic piano bloom

That singing piano bloom when a note opens up starts with real voltage swing – real headroom. King Cobra holds the same alive feel as the classics, only tuned for what comes next.

Neither Head nor Combo

KING COBRA – Neither Head nor Combo

Compact, strong, and ready for any cab or pedal setup. Reverb or echo in front or loop – both work, just different attitude.

Four Knobs, Two Switches

The King Cobra Control Panel

Gain, Lo, Hi, Vol set the voice and power; Pres. tames/adds top shimmer; Core shifts the power feel – 20/50/100 W, triode↔pentode.

The Voice – Clean To Mean

Voices Of The World

British bite, American depth – both and beyond. Clean tones shimmer, driven tones growl. Pedals blend right in – Himmelstrutz or not.

Phase Inverter Mystery

Das Phase Inverter – Mother Of All!

Clean, mean, and everything between doesn’t come from one stage – it’s the whole chain waking up. Preamp shimmer, phase inverter  bounce, power-feel movement. King Cobra has that same reaction built in, with a touch of Balthazar magic.

King Cobra Recording

King Cobra Amp
RECO

Use 1 or 2 microphones to record King Cobra through a cab or go direct through Himmelstrutz RECO. Same feel, same honesty, quiet neighbours.

We Love Valves, Time Moves

Valves are great – have been for ages. But time doesn’t stand still; it moves. King Cobra keeps the spirit – loses the fragility – evolution that finally makes sense.

Frank Zappa once made it clear

Any Downsides vs Valve Amps?

We searched for drawbacks. Found the usual feel, none of the usual burdens. If there’s a downside – it lives somewhere we have not found.
