The Electro-Harmonix Freeze pedal delivers infinite sustain of any note or chord at the press of a momentary footswitch. Release the footswitch and you are again sample ready. Three selectable decay rates, including a latch mode, guarantee liquid, smooth tonal transitions.
Craig Anderton has written an interesting review of the Electro-Harmonix Freeze pedal, concluding:
The fact that Freeze works with just about anything is a standout feature. For live performance you can sustain a chord and solo over it, not unlike a looper but Freeze works on a more granular level – it sounds like the same kind of process you’d use to create a perfect crossfade loop.
Freeze is really one of the more creative effects I’ve heard in a long time. It’s not for everyone, and realistically, it does only one thing. But it does that one thing really well, and really cleverly. What’s more, it’s the kind of box that encourages experimentation – for example, it may end up being the ultimate tool of all time for creating synth pads. No matter how you use it, though, there’s no denying that Freeze is unique and very, uh, “cool.”
The Electro-Harmonix Freeze retails for about $120.
