1970s Electro-Harmonix Small Stone Phaser Pedal

Aside from the case machine screws on top, this guy appears to be all-original. It's working 100% and ready to go, too. I love how much wear and tear the box has, too -- it's definitely been used heavily!

These pedals are very simple but, when you jack one in, you immediately recognize their sound from zillions of old recordings. There's something to be said for keeping things easy-peasy on the panel. You can dial it in and just go.
