The Garnet B260D BTO Bass is a 260-watt bass amplifier from the BTO series, developed with Bachman-Turner Overdrive for the punishing low-end demands of stadium-level rock touring. Fred Turner's bass playing in BTO required an amp that could compete with the band's enormous guitar rigs, and the B260D was Garnet's answer.
