Hey. I have an MTD Kingston Saratoga 5-string bass. I've had it for a little while now and it is perfect...except for one thing. The A string does not have the sustain or liveliness that all the other strings do. I replaced the stock strings, didn't like that set, and put the stock strings back on. This is when I first noticed the issue. I thought maybe the strings were just old, etc., so I got a new set...same issue. I've looked at the instrument from the tuner, to the zero fret, and to the bridge and cannot spot any reason this should be occuring. Any one else experience this issue with a bass? What would be recommended? A professional setup perhaps? I'd like to see if you guys can help me out before I go rambling to a professional for what could possibly be an easy fix. Any help is appreciated!
