Electro-Harmonix FREEZE Sound Retainer PedalCount on the mad geniuses at Electro Harmonix to give you the power to freeze and hold your guitar's notes and chords for as long as you like! The aptly named Freeze sound retainer pedal lets you play a note or a chord, hit the pedal, and freeze that sound in sustained place, indefinitely. You can choose between fast or slow decay to let the sound fade out. Or choose the Latch function and let the sound continuously sustain for as long as you like.
