Recording from a Taylor 501 - LE

[Mikeskids]

Hi Guys. I'm a novice to recording and a bit of an old boy so don't understand the lingo!!!!
I'm trying to record on Garageband ( just voice and guitar). I'm finding that my guitar sounds good on the low strings but the higher strings sound a bit tinney.
Is this a common issue and what can I do about it.
I've looked at interfaces to plug in two mics but to be honest I find it all a bit confusing. If this is the solution and I don't know whether it is, I don't have a lot of money to spend so can anyone recommend the right set up budget wise. I'm only recording for myself not for commercial reasons.
Any help gratefully received
Mike
