Enhancing Ovation Gtr Sound In Digi001, Gtr sounds tinny and signal levels vary Options

[Tone]

Being VERY new to VST/Audio Recording I would firstly congratulate you on a helpful and informative forum. I am using the Digi001-MacG4/733-Korg Triton Le MWS at home in Shanghai. The budget is all but gone. Although the overall reults are satisfying I still cannot get a decent sound using my Ovation. The signals vary and the sound is tinny and unnatural no matter how much I adjust the controls on the plug-ins that came with the 001 (Delay etc). Is there an 'alternative' to further purchases of costly equipment to get some realistic gtr sounds into the songs - accoustic chord/rhythm as well as lead?. (As a Brit Expat the local options are impossible to track down).
Thanks again
Tony

gdoubleyou & damann, many thanks for the advice
You both hit the nail~. All my equipment (inc Sure Mics and Effects etc) are still in England and not here at my home in China. Being reluctant to pay out all that money on the same equipment I already have even if I could find it in Shanghai, I borrowed a cheap mic which is not the best for my needs. (I am a 10 month 'newbie' still at the trial stage). Anyway now I have an answer, and more importantly direction, thanks to the forum; To get the best sound there is no 'quick-fix' thru software signal correction and I need to purchase the best equipment to get the required sound BEFORE I RECORD into my ProTools (DIGI 001/LE 5.1.1).
Thanks again
Tony
[PS; Sorry to be a painful newbie but, to understand and learn more, could I ask the forum, just for the next week or so, to put the full names in brackets next to the shorthand initials used, So I can get up to speed with the tech terminology - ie " VST (Virtual Studio Technology)". If time does not permit I fully understand.]
