Info about the original:
The Paramount Overdrive is a Medium Gain (Second Stage Overdrive) that stacks very well with almost any pedal. It can be ran at 9-18v (18v for more headroom). The Paramount is an original Emerson circuit that is powerful has plenty of usable gain on tap to fit most any situation. The Paramount's character is refreshingly unique yet sits in the mix very well and has a familiar sound. This pedal is very dynamic and responds well to pick attack and the subtle nuances of the player.
