Jimi,
I don't do Gearbox, but I've recorded a lot of acoustic guitars, many different ways. I will say that mic'ing usually gets the best results, with the right type of mic(s) and mic technique. So...what mic's do you have...and describe your 'room'...there's possibly some cheap work-arounds I can suggest - unless you live in a Train Station, a harbor, or under a major highway underpass.
But...and I have 2 a/e Tak's myself...recording direct can produce decent results. Again, there's some tricks involved.
And then there's doing both at once...
We have a time-lag here, and I'm about to go to work, back in about 12-14 hours from now...someone else will probably step up and give you some good advice here...
^^
