Crazy Tube Circuits - HI POWER

Crazy Tube Circuits - HI POWER

HI POWER is our next endeavour in pedal + amp-in-a-box overdrives inspired by the sonic combination of two British tone machines that helped shape the sound of Pink Floyd’s Wish You Were Here Album.

On the right side of the pedal, you will find a recreation of the Colorsound Power Boost featuring the true-to-the-original spec BC184 transistors running on 18V DC (via an internal voltage booster circuit) and the ultra-flexible 2-band Baxandall EQ circuit. We’ve added extra features, like a bypassable master volume control, a reverse-log gain control to ensure better sweep and transition from clean to mean (compared to the original’s linear taper) and a toggle switch the engage the latter higher gain / lower headroom version of the original boost circuit called Overdriver.

On the left side of the HI POWER you will find an all-analog circuit set out to emulate the sound and feel of a Hiwatt amp. Following the path of the famed British tube amplifier our circuit offers authentic amp tone and feel. From the big bold high-headroom clean sounds to the face-melting crunchy tones.

True to the last detail we have included the full EQ section along with a presence control located at the negative feedback of the power amp simulation circuit. A headroom toggle switch selects between the high headroom 100w power section provided by a quartet of EL34s or the lower headroom and compression provided by a 50W power section with a pair of EL34s when hit hard. Similar in operation to the original amp design the master volume control was designed to produce more gain at higher settings.

We’ve taken our 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 of the amplifier, 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.

Like our other dual overdrive/amp-in-a-box designs we have also included a passive effects loop to give you the option to connect your beloved pedals between your booster/overdrive and amp in a box or use the two sections as separate and independent effects when using an external bypass switcher/looper.

HI POWER also features a power-up bypass/engage pre-set function for the onboard footswitches. That way you can select which state your pedal will go to when you plug the power supply. This function comes in especially handy to people that use remote pedal switchers / loopers as they only set the power-up state of the pedal once and then operate from the controller

FULL FEATURE LIST :

- All-analog dual booster/overdrive – amp in a box.

- Recreates the tones of the legendary setup used by David Gilmour in the recordings of Pink Floyd’s Wish You Were Here album.

- Right side: faithful reproduction of the Colorsound Power Boost/Overdriver circuits with true-to-the-original-spec BC184 transistors.

• Controls: volume, bass, treble, master, voicing toggle.

• Wide volume (gain) range control: from transparent boost to gnarly and fuzzy overdrive.

• Two band (treble & bass) Baxandall EQ.

• Master knob sets overall output. Huge amount of dB boost available. The earlier units of this classic pedal didn’t feature this control. We’ve set it that way so it when it is maxed out it resembles exactly the circuit of those early units.

• Toggle switch to select between the 18V Power Boost style circuit or the 9V Overdriver style circuit.

- Left side: Hiwatt AMP in a box overdrive.

• All analog simulation of the preamp and power amp sound and response.

• Controls: volume, bass, middle, treble, master, input channel toggle switch, headroom toggle switch.

• Volume (gain) control: from clean to big bold British crunch/overdrive.

• 3 band Hiwatt style EQ (bass, middle, treble).

• Presence control follows the original design/is located at the negative feedback of the power amp simulation circuit to control the amount of upper mid and high frequencies.

• Master knob sets overall output volume. Designed to respond like the original control producing more gain at higher settings.

• Input channel toggle switch selects between normal, bright, or linked input channels of the AMP for different voicing and gain levels.

• Headroom toggle switch selects between the high headroom and dynamic response of a 100W amp or the lower headroom and compression of a 50W power amp.

- Independent operation of the BOOST/OVERDRIVE and AMP sections

- Click-less true bypass design via high quality relays for each section.

- 2 Footswitches/2 Status LEDs - one for each effect section.

- Power-up bypass/engage preset function for the footswitches.

- Power Supply: Use only 9V DC, 2.1 mm x 5.5 mm, center negative (not included).

- Runs internally at 18V DC (via voltage doubler circuit) for higher headroom and tube-like performance

- Current consumption 84mA.

- British Racing Green die-cast enclosure with colour-coded lettering for the control section (orange for BOOST/OVERDRIVE section, white for AMP section).

- Dimensions: (W x L x H): 119 x 97 x 53 mm.
