MusicRadar Verdict

This is a great source of breaking-up amp sounds and a useful option for adding boost to another overdrive pedal.

Pros

  • +

    Subtle variations in low gain overdrive. Compact size. Musical tonal range.

Cons

  • -

    Four-screw battery access.

The Helium takes the Jetdrive as its starting point, but is more than just a single-channel version of that pedal.

Indeed, as well as having a less powerful gain range, the Helium also sports a tweaked bottom end.

Sounds

The overdrive available on the Helium is organic, natural and sounds more like what happens when you turn up or switch a channel on a valve amp than a pedal-based effect.

The lean/rich tone control works in a specific frequency range that makes it nigh on impossible to dial in an unusable sound, but still offers the chance to soften it or make it more aggressive.
