‘The Voice’ contestants Zach and Colton Swon stood in front of a packed studio audience and 10 million TV viewers and performed Nitty Gritty Dirt Band’s ‘Fishin in the Dark’ playing their Tak P7D and EF360SBG respectively. The performance helped them advance to the competition’s final 12 and a live spot on next Monday night’s show. The Brothers from Oklahoma have been Tak fans since childhood, cutting their teeth on their father’s SW341 Steve Wariner model.
