The Halo Chorus is a combination delay/pitch modulation/phase modulation chorus design with autoconfigurable I/O for mono, mono in/stereo out, and stereo in/stereo out operation. The combination of pitch and phase modulation can be used together or individually for traditional chorus sounds or unique, spatial tones.
In addition to the top mounted controls there are two user adjustable internal controls (delay time and LFO wave shape) that allow for fine tuning of the chorus from deep and syrupy to light and airy and all points in between.
The stereo ins and outs with independent pitch and phase modulation signal paths allow for a wide variety of parallel and serial configuration options.
Features:
Parallel combination of delay / pitch modulation and phase modulation gives versatile control over modulation effects from light chorusing to deep 'vibey' swirl
Stereo operation gives wide stereo image spread while preserving the original guitar tone
NOS MN3007 analog bucket brigade chip running at 15V rails for extended headroom
Dual opto 'vibe' phase modulation path also running at 15V rails vall analog circuitry
Autoconfigures for mono, mono in / stereo out, and stereo in / stereo out operation
Pure sinusoidal LFO using a dedicated function generator IC for smooth modulation with variable 'SPEED' and chorus pitch modulation depth 'CH DEPTH'
'CH MIX' and 'PM MIX' controls allows independent control of chorus and phase modulation mix levels in both mono and stereo configurations
Kill-dry switch for parallel FX loop operation or use of chorus path for pure vibrato
Mono input signal passed through to both outputs on bypass
Phase switch to invert phase of right channel output relative to left
LED indication of LFO speed
Expression pedal control of LFO speed
Same Vishay JFET / audiophile BurrBrown opamp signal path as in Memory Lane delay
Telecom grade relay switched true bypass operation on all inputs and outputs
Internally regulated to 15V, can be run from provided 24V adapter or from 18V pedal board power supply outputs (including Y-cable powering from 2 9V outputs on the Voodoo Labs Pedal Power 2 Plus, Burkey Flatliner or other compatible power supply)
