Gretsch 6160 Chet Atkins Country Gentleman 2x12 amp | The wwwearpage›Home›Forums›The GearJun 08, 2016It's a Gretsch 6160 Chet Atkins Country Gentleman 2x12 amp. I'm totally taken aback by it's available tones and features. Unlike anything I've ever owned before. For starters, it's got a unique input scheme. There are six inputs to this amplifier, one being a 'phono' input the rest regular, which feed into two separate amplifier channels.
