Well, thank all of you for sharing your thoughts. I know capturing the acoustic guitar sound is worth putting some time into. For instance, one guy that used to record me mic'd the guitar straight toward the hole like we have all seen, then he took another mic and pointed it straight down from the top about even with the hole. I had never seen that before. Then mixed them together for a good sound.
I may have to retire my fx-500, it is very old, and kind of noisy anyway. I had to hardwire the power switch to "on" years ago, all the ins go right to the board. Not really a well built unit.
Mac said about $100. for the LR Baggs I beam.
Ok I will look for this I Beam thing on Musician's friend, or locally, and see what happens. I have been an acoustic player for much longer than electric, so I just want to put all my effort in to that of course. I get too ranchy when I play electric. I don't know how to play to clean. Probably from my rock and roll daze.

Well thank you guys for sharing your secrets, it is helpful.
