So compressioin is not really clipping off the highs and lows, but just expanding the sound across the range? I'll read that link you gave me Andrew.
I'm not good at guitar at all. I always wanted to play but never took the time until several years ago when I met a guy who played real well. I said, "It'll take a year before I can even play anything." He looked at me and said, "Well... a year will go by anyway. A year from now, would like to be able play something or still just sit their and wish you could." I went to SamAsh and bought two guitars that day.
I knew very little and just picked out he electric that looked really good and felt really good. I had never heard of PRS before, so I was actually tihnking I was buying an off brand. I was pretty ignorant at time. But I liked it so much and I figured that I'd want to pick it up everyday just because I thought it was so cool and that helped me stick to it a bit.
It seems that when I crank up the compression on my effects rig, my playing definately sounds better.... maybe because it masks the mistakes better?
