Valbruch Kaluna High Voltage Tube Drive

Selling a Valbruch Kaluna tube overdrive. This is the V1 version. Comes with original box. Has a JJ ECC83 installed currently.

Description:

The Vahlbruch Kaluna is a handmade, high-voltage tube overdrive and distortion pedal for electric guitar. Designed in Germany by Dr. Henning Vahlbruch, it features a real ECC83/12AX7 double triode tube running at a true 250 volts internally while powered by a standard 9V (500mA) external supply. [1, 2, 3]

Key Features and Design:

• True High-Voltage Tube: Runs the internal tube at 250V for genuine, organic compression, touch sensitivity, and harmonic richness. [1]
• Active 3-Band EQ: Post-tube bass, middle, and treble tone controls offer +/-12dB boost or cut to tailor the sound to your amp. [1]
• MagTraB Switching: Uses silent magnetic-sensor foot-switching technology connected to gold-plated relays to eliminate mechanical popping. [1]
• Gain Structure Switch (Kaluna II / V2): Allows you to toggle between different gain modes, including Low, original V1, and Hot saturation settings. [1, 2]
