Chord triads are useful in country, they help create rhythm variations.
A triad uses 3 notes from the major or minor scale, the Root (1),the 3rd(3) and the 5th (5). These notes make up a major or minor chord in its simplest form.
Use the bridge and neck pickups, for country rhythm sound. Software used for this kind of sound is Guitar Rig 5 with a factory preset - Country Twang Clean.
