Well, I may have solved part of my own problem with the feedback. Up until last night, I had only played the acoustic plugged in at church, where I sit very close to my amp. Last night, I played my first gig outside of the church and was out front walking around. Guess what, no feedback. Duh.
I really enjoyed playing last night. That was my first outside gig playing acoustic plugged in where I had everything working right. I took my electric along, but it never came out of the case. I enjoyed the acoustic so much, that I played the whole show with it.
Also, the problem with the D string being of lower volume was apparently the old string. New strings before the show last night solved that problem.
So, you guys are a lot of help.
I guess my questions were so stupid that no one had the heart to tell me so. But, I tell you, I am enjoying playing the acoustic so much, that now I am hot for a nylong string. Stay tuned.
Merry Christmas everyone.
