Keep practicing!! That will help your fingers callous! That is probably the biggest reason people quit the guitar, because it hurts your fingers! I started playing again after a long layoff, I knew what to expect. I've been playing for about 2 months now, EVERYDAY! I have a nice set of callouses, but there is still some pain. Of course I play for about 2-3 hours sometimes! Try using aspirin internally and Witch Hazel for your finger tips to ease the pain a bit. I also use hand softener on them daily to keep the callouses pliable so they won't crack and bleed. Keep the nails trimmed and filed back, (not too close to the quick though) so they won't snag on the strings. Practice 1%, fun 99%, don't give up! I have an "Esteban" cutaway acoustic/electric, Epiphone "Les Paul" Junior Solid body, Squire (Fender)"Affinity" Series Telecaster Special Edition,(I prefer to play the Tele) and a Line 6 "Spider III" amp. The amp has four preset push button settings and echo, reverb, clean, and a Mp3 hook in, in a 15 watt package. Not a bad little practice amp for $100 new. Sorry I don't think I can help you too much on your settings. I use the clean setting with a slight echo to it. then I play with the guitar's tone to get the exact sound that I'm looking for. My guitar heroes, Clapton, Santana, Robert Cray, Chuck Berry, George Harrison, Keith Richards, Tom Petty, Johnny Cash, Bo Diddley, and my cousin "Catfish Keith" (nominee for J.C. Handy Award for Mississippi Delta Blues slide guitar artist).
