I changed my 70's Nat. LP with 59's 10 years ago. Sounds very clean in my Fender reissue Blues Deluxe but I can't get that warm feeded back out of it like I got out of a friends standard Les Paul. Is the pick-up not HOT enough, to HOT or is it something with the amp which has been recently set up? Please help I am a player not a ele. junky.
