The sound of Pink Floyd's Wish You Were Here in a pedal!

The Hi Power painstakingly replicates the classic gear that shaped Pink Floyd’s classic Wish You Were Here album.

On the right side, you will find a recreation of the Colorsound Power Boost, featuring true-to-the-original BC184 transistors running at 18V and an ultra-flexible 2-band Baxandall EQ circuit.

Crazy Tube Circuits added extra features, like a Master volume control, a reverse-log Gain control (to ensure better transition from clean to mean) and a toggle switch that engages a higher gain mode.

On the left side of the Hi Power, you will find an all-analog circuit set to emulate the sound and feel of a Hiwatt amplifier.

Following the path of the famed British amplifier, the circuit offers authentic amp tone and feel. From the big bold high-headroom clean sounds to the face-melting crunchy tones!

A Headroom toggle switch selects between the high headroom 100W power section provided by a quartet of EL34s, or the lower headroom provided by a 50W power section with a pair of EL34s.

Similar in operation to the original amp design, the Master volume control was designed to produce more gain at higher settings.

Crazy Tube Circuits took the design a step further by adding a switch to select between input channels.

You can select between the full frequency response of the Normal channel, the increased presence and tight low end of the Bright channel input or the enhanced frequency response and added gain of those inputs linked together!

The pedal also features an FX loop to connect pedals between the two sections or use them as independent effects with a switcher.

Best Amp in a pedal I have tried !

This is definitely the best amp in a pedal I've tried, since I plugged In the Hi power, a few other amp and overdrive pedals have been jupming out of my pedalboard.

Excellent unit

The boost/OD side is one of the finest I’ve played. Unique pedal that has no real peer.

Anup Negi

Alberto Della Porta
