I'd use one, the 2020 probably, and just find the right spot to get the balance of mellow tone plus the right amount of neck sound. Realistically, when we've done guitars before, people often blend two mics for the different tones, but this doesn't make it stereo. Hard panned left and right from two mics creates guitars many feet wide, when they're not. Very gentle panning off centre and adjust the balance of multiple mics to 'create' the right sound.
