Each Beatle played a range of acoustics. Paul used an Epiphone Texan and a Martin D-28; early on John had a Gibson J160-E, for nylon works a Ramirez A-1, a Framus for 12-string and later a Martin D-28; George also used J160-E and a Ramirez, and on later albums a Gibson J-200. Of course, any model will be fine. The above settings are a guide for when using acoustic amps.
