hey all. i just got my fender p bass set up. anyway, when i brought it home, i immediately noticed that the string tension was much higher. it is very noticibly harder to pluck the strings. i've never had this happen before. AND.. i use a roundcore string (fender super 8150), which have always been VERY flexible. so i was wondering.. is this due to the set up? is it something with the neck? i'm very confused. i even had him adjust the neck AGAIN.. it the problem persisted. HELP!
