Treble Charger was a Canadian rock group from Sault Ste. Marie, Ontario, Canada, formed in 1992. The band consists of vocalist Greig Nori, bassist Rosie Martin and drummer Trevor MacGregor. Guitarist Bill Priddle, a founding member of the band, left in 2003. They began with a melodic indie rock style, but have evolved into more of a pop punk band since signing to a major label in 1997. The band was originally named NC17 but had to change their name due to some dispute with a US band of the same name.
