Vahlbruch Kaluna High Voltage Tube Drive

Vahlbruch KALUNA : High Voltage Tube Drive

The 100% analog circuitry of the Vahlbruch Kaluna is based on a 250-Volt ECC83/12AX7 double triode tube. The high voltage required for this type of tube circuit is generated internally from the standard 9V power supply and is responsible for the rich overtone content, the certain overdrive transparency, the percussive attack response and the typical complex compression, which also characterizes boutique tube amplifiers when overdriven.

The Kaluna has a flexible active three-band tone control, which inside the circuit is placed after the tube. Thus it is the perfect tool to perfectly match the sound spectrum of the pedal to the guitar, effects chain and amp setup used. KALUNA thus allows a wide range of distortion characteristics from mild breakup sounds to creamy saturation. This versatility is paired with an exceptionally open sound characteristic, a high transparency and an extremely wide dynamic range that allows for a very direct and natural interaction with the player. Due to this unique circuitry, the overtones always appear homogeneous and musically harmonious, making the guitar sound extremely organic, "catchy" and three-dimensional, without dominating the actual sound character of the guitar and/or the amplifier.

In only 4 steps you can choose if the pedal powers up in "true bypass" or "on"-mode:

• Step 1: Disconnect the power supply.
  
• Step 2: Hold down the "MagTraB" button.
  
• Step 3: Reconnnect the power supply, while remain pressing the "MagTraB" button.
  
• Step 4: Release the "MagTraB" button.
  

In order to undo the programming, simply repeat the steps 1-4. The next time your pedal powers up, it will automatically start in "on" in "true bypass" mode, just depending on what you have stored.
