CRAZY TUBE CIRCUITS HI POWER
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: gain, bass, treble, master, voicing toggle.
Wide 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.
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: gain, bass, middle, treble, master, input channel toggle switch, headroom toggle switch.
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.Features:
- 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.
- Top-mounted jacks
- Passive series effects loop to connect pedals between the two sections or use them separately as independent effects.
- 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 color-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.
- Weight: 444 g.
- Made in Greece.
