About this listing
Experience the iconic British tones that defined a generation with the Crazy Tube Circuits Hi Power. This premium overdrive and amp-in-a-box unit recreates legendary sounds inspired by the fusion of two classic tone machines: the renowned Colorsound Power Boost and the high-headroom Hiwatt amplifier. A favourite among guitar legends, the sonic character of this pedal echoes the celebrated guitar solos of Pink Floyd’s Wish You Were Here era, delivering endless sonic possibilities for professional musicians and enthusiasts alike.
Main Features
Authentic British Tone
Captures the classic Coloursound Power Boost’s transparent clean boost and full-on fuzz, utilising true-to-original BC184 silicon transistors running on an 18V internal booster circuit for enhanced headroom and dynamic response.
Flexible 2-Band Baxandall EQ
Shape your sound with precision by adding bite, midrange clarity and deep low-end rumble to tailor any guitar setup.
Master Volume Control
Unlike early Power Boost units, Hi Power includes a master volume knob that bypasses when wound fully clockwise, enabling refined control over boost and overdrive levels.
Hiwatt Amp Emulation
An all-analogue circuit section impeccably simulates the legendary tones of the Hiwatt tube amps, offering everything from pristine clean sounds to rich, crunchy distortion.
Selectable Headroom
Switch between a high-headroom 100W style power section using four EL34 tubes or a compressed, dynamic 50W style with two EL34s to replicate classic Hiwatt responsiveness.
Three Input Channel Modes
Choose the normal channel for full response, bright channel for added presence and tight lows, or combine both channels for an enhanced gain and frequency boost reflecting David Gilmour’s personal amp modifications.
Passive Effects Loop
Integrate your favourite pedals seamlessly between the booster and amp sections or use the pedals independently with an external looper. All pedals remain active even when Hi Power is bypassed.
Power-Up Preset Function
Customise the default on/off state for each footswitch on power-up. Ideal for use with remote pedal controllers or loopers.

Frequently Asked Questions
➤ What iconic tones does the Hi Power recreate?
The Hi Power recreates the classic sounds of the Coloursound Power Boost and Hiwatt amplifiers famously used by David Gilmour and other legendary British guitarists, offering everything from transparent boosts to rich tube-driven overdrives.
➤ How does the effects loop work on the Hi Power?
It’s a passive loop allowing you to connect other pedals between the overdrive and amp sections or use the sections separately when controlling via an external loop switcher. Pedals remain active in the chain even when Hi Power is bypassed.
➤ Is the master volume control true to the original Power Boost design?
Unlike original Power Boost pedals—which lacked a master volume—Hi Power includes this control for precise adjustment of overall output, with a unique setting that bypasses the volume when fully turned up.
➤ Can I switch between different amp voicings?
Yes, the pedal offers three input channel modes: a normal channel, a bright channel with increased presence, and a combined channel inspired by David Gilmour’s customised Hiwatt amps to deliver a broader tonal palette.
➤ What power supply does the pedal require?
Hi Power runs on an internal 18V DC booster circuit, delivering the correct voltage and headroom for authentic BC184 transistor operation and amp simulation.
