Agreed............the high E thing is normal. As far as sustain, could be fretting out as you suggested, or perhaps the pick up height is too high. Maybe the magnets are sucking up the string. Squeeling? Too many varibles, i.e. EQ'ing, volume in relation to where your standing, pick ups, amp, so on & so on......
I had a Universe that didnt really squeal, but because of the front recess, you could hear alot of body noise. I stuffed tissue paper in the cavities and it quieted it down massively. Have no idea if any of that helped...............but there ya go. Theres my 2.5 cents
