Halo Chorus

The Diamond Pedals 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. It features a parallel combination of delay/pitch modulation and phase modulation, providing versatile control over modulation effects from light chorusing to deep 'vibey' swirl. The stereo operation gives a wide stereo image spread while preserving the original guitar tone.

Technical specifications include the use of NOS MN3007 analog bucket brigade chip running at 15V rails for extended headroom, dual opto 'vibe' phase modulation path also running at 15V rails, and all analog circuitry. The chorus also features a pure sinusoidal LFO using a dedicated function generator IC for smooth modulation with variable 'speed' and chorus pitch modulation depth 'ch depth'. It has controls for 'ch mix' and 'pm mix' that allow independent control of chorus and phase modulation mix levels in both mono and stereo configurations.

Other features include a 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, and expression pedal control of LFO speed. The chorus is internally regulated to 15V and can be run from a provided 24V adapter or from 18V pedal board power supply outputs.

The Diamond Pedals Halo Chorus comes in a genuine Hammond cast aluminum case and offers a comprehensive set of features for creating rich and versatile modulation effects.
