What's your opinion about delay (or other?) pedals that do the freeze/hold thing? Example would be end of the solo in Rush's Limelight where the high bent note is held while Lifeson goes back to playing the arpeggio.

I like the looks of the EHX Freeze, but I'd really prefer to have more than one capability from a pedal taking up space on my board.

What pedal have you used/liked for this?
