If that was the guitarists impression then I might try a stereo set up about 30" from the guitar body.
If you do that you'll need to work with placing the musician in your room so that the guitar sounds best and the mics are in a good sounding place to.
Close micing works well in most rooms but not everyone is interested in that sound. Near-far micing is great for getting a natural, familiar sound, but you have to assure that the natural sound is pleasing and some rooms make that difficult.
Keep it positive and help the guitarist find what they are looking for.
best regards,
