Two iconic British circuits, one powerful pedal.

The Hi Power by Crazy Tube Circuits combines a faithful recreation of the Colorsound Power Boost with a Hiwatt-inspired amp simulation, delivering dynamic gain staging and authentic British amp tones. With independent footswitches, flexible EQ controls, and a passive effects loop, Hi Power offers everything from transparent boost to full-stack saturation.

Key Features

• Colorsound Power Boost Recreation – True-to-original BC184 transistor circuit, running at 18V DC via an internal voltage booster.

  • Master Volume Control – Allows better control over output level.

  • Reverse-Log Gain Control – Provides a smoother transition from clean to mean compared to the original linear taper.

  • Overdriver Mode – A toggle switch engages the higher-gain, lower-headroom version of the original boost circuit.

• Hiwatt Amp Simulation – Emulates the bold, high-headroom clean tones and crunchy drive of classic British amps.

  • Full Amp-Style EQ – Includes Bass, Treble, Presence, and Master Volume.

  • Selectable Input Channels – Choose between Normal, Bright, or Linked modes for varied tonal shaping.

  • Headroom Toggle – Switch between 100W high-headroom power section (quad EL34s) or 50W lower-headroom compression (dual EL34s).

• Passive Effects Loop – Allows integration of external pedals between the boost and amp sections, or independent use of each section via a bypass switcher.

• Power-Up Preset Function – Lets users set the default state of the pedal when powered on, useful for remote pedal switchers.
