The Kaluna II HV is a seriously cool little tube pedal. It nails that warm, responsive overdrive sound, and the new structure switch really expands its versatility. This is a great option for guitarists wanting a genuine tube feel without the fuss of a full amp – especially those into rock, blues, and slightly heavier genres.

Frequently Asked Questions
The ‘HOT’ setting provides higher gain for more aggressive distortion, while ‘LOW’ offers a smoother, more subtle overdrive tone.
While it uses a standard 9V barrel connector, the high current draw (500mA) means a dedicated, isolated power supply is highly recommended for best performance and reliability.
The Kaluna II offers a genuine tube saturation characteristic which is impossible to fully replicate digitally; it has a more organic, responsive feel and harmonic complexity.
