I heard a music bump between news stories on the radio yesterday. Just an electric, for just a few bars. I want that sound. I don't use pedals much and for OD I have a Barber LTD that does lo-gain very well. The sound I heard had a crystalline, rattly quality and didn't color the Strat guitar tone at all. Not buzzy, compressed or even consistent, the level of effect faded as the notes decayed.

What kind of pedal will give that?
