Vahlbruch - KALUNA High Voltage Tube Drive

Vahlbruch KALUNA : High Voltage Tube Drive

The Valbruch KALUNA is a new and completely original design featuring an ECC83/12AX7 tube that is 100% pure analog tone! Operating at 250 volts, the dual triode tube circuit is powered by your standard 9V power supply, producing this very particular sweet harmonic content, overdrive clarity, fast pick attack response and complex compression, that we all love from cranked tube amps. The KALUNA is a super versatile, intuitive drive pedal with an extremely open sound that's transparent with great dynamics. The gain characteristics from the KALUNA are organic and three dimensional, delivering mild breakup to creamy saturation.

The KALUNA's unique circuit bears extraordinary touch sensitivity. Every musical nuance generated from your picking attack is exactly reproduced. The post tube, three band tone controls are extremely responsive, which is perfect for tailoring your tone to your specific gear and sound.

The Vahlbruch KALUNA tube pedal definitely sounds different compared to solid state pedals and with its great clarity it will never mask the natural sound of your guitar and amplifier.

This pedal is equipped with my unique Magnetic Transducer Button = "MagTraB" switching technology:

Inside the button a magnet is integrated which position is measured by a sensor on the circuit board. If the button is now moved, e.g. if it is pressed downwards, the position of the magnet will also change. The sensor measures this change without any mechanical contact to the button and the information is send via a micro-controller to a gold-plated relay, which then does the actual audio signal switching. The advantages:

MagTraB buttons are as good as indestructible!

MagTraB delivers an almost infinite number of switching cycles - many, many millions!

No annoying, mechanical switch clicks!

Instead, the "MagTraB" push-buttons switch very smooth and quiet!
