Im trying to figure out the best way to record guitar on a tascam portastudio when using 1/4 inch unbalanced inputs. I have a Fender Blues Guitar amp with a preamp out jack. Is it better (when using a 1/4 inch input) to mic the amp or to run a line directly from the preamp out on my guitar amp to the input on the portastudio. I am using a tascam 488 Mk II. Although it is an 8 track recorder, only the first two inputs use the 3 pronged balanced inputs. Tracks 3-8 are 1/4 inch inputs. Thanks in advance for any suggestions.
