As mentioned in the other question mentioned above, omitting the article usually implies "play the __ part", e.g. in an orchestra, chamber group etc -- in other words it focusses on the actual music-making. Including the article refers more to the physical action/ability of playing.
Usually (I think), when there is a determiner the before a noun, we're talking about a specific thing referring to the noun (in this case a guitar). But this is a phraseological analysis and I don't think it's the case for this sentence … maybe there's no difference at all … anyway, it depends on the context.
P.S. Sorry for my English not really perfect ;)
