The HV30™ utilizes an exclusive new preamp circuit that combines a 12AX7 vacuum tube known for its robust tonal qualities with solid-state circuitry that provides consistency and reliability. To maximize the tube's distinctive audio characteristics and dynamic range, the exclusive Kustom HV preamp circuit operates at high voltages. The resulting tone is rich, dynamic and loaded with harmonic content.

The HV30 features 30 watts (RMS) of output power combined with a 12-inch Celestion™ guitar speaker. It provides two channels, each with Gain and Master Volume controls. This Dual Master system lets players easily get natural tube overdrive and compression on the Rhythm channel as well as the Lead channel. The HV Series EQ consists of passive Bass, Middle and Treble controls that are the same specifications as Kustom's award-winning, all-tube Coupe™ amplifiers. The HV Series' speaker-emulated Direct Out and variable Volume Boost controls are also borrowed from the Coupe.

An all-new 24-Bit Digital Multi-Effects System has been created exclusively for the HV Series. It offers 16 hi-fidelity, programmable effects with increased flexibility thanks to Tap or Toggle functions for each effect, letting players fine-tune their choices. For example, Delay times, Reverb tails and Tremolo speeds can all be tapped to desired settings. Alternately, the Spring Reverb effect can be toggled between three different tonal selections; the Rotary Speaker can be ramped between speeds; and the Octave selection can be toggled to choose Octave Up or Octave Down.
