Clock noise issues are reported, especially with non-true bypass models and certain power supplies, suggesting sensitivity to power source quality.

Users report distortion issues with T-top humbuckers, even in low sensitivity mode, suggesting challenges in maintaining a clean chorus tone.

The PastFx Chorus is noted to have a rare chip in the Deluxe version, though sonically perceived as similar to the standard model.

The PastFX Chorus is regarded as a closer replica of the original Boss CE-1 than the CE-2W, particularly due to its inclusion of the CE-1 preamp.

The Retro-Sonic Chorus is noted for having a modified preamp for higher headroom, potentially offering a cleaner alternative to the PastFx Chorus.

Users aiming for John Frusciante's tone suggest placing the Chorus Ensemble just before a Holy Grail Reverb in the pedal chain.

One user praises the chorus tone as the best they've experienced, surpassing the Boss CE-2w, noting its warmth and lushness.

Loud popping occurs when activating or deactivating the pedal in true bypass mode, making it impractical for some users.

The pedal requires the bypass foot switch to be pressed twice upon power-up to pass the signal, due to relay complexity.

The vibrato mode is highlighted for its ability to create unique sounds, particularly effective for solos and experimental song elements.

Switching to the 500k pot mod enhances the brightness, making the tone nearly as bright as a direct signal.

Adding an external buffer does not resolve distortion for some users, indicating limited success in modifying the signal chain for cleaner tones.

The preamp stage can be adjusted to add crunch, with users finding optimal settings around 11 o'clock for clean tones.

The mini version of the pedal shares distortion issues and clock noise, indicating consistency in design limitations across models.

The PastFX Chorus Ensemble Deluxe includes a "500K Pot Mod" for better compatibility with guitar signals, which can be toggled on or off.

Some owners experience volume drops when turning down the level knob to clean up distortion, indicating potential issues with maintaining unity gain.

A "Depth mod" allows control over the depth of the chorus effect, unlike the stock CE-1 behavior.

The pedal features an input buffer to reduce impedance, enhancing treble retention in the signal.
