I LOOOOOOVE my Stingrays.
My best ever sounds for LIVE use are SR4 or SR5, into a Sansamp BDDI, into the PA, and into my MArkbass LM2 and Mb 4*10 cab.
Now, I use the Sansamp on 50/50 blend - 50% direct bass sound, for the middy "bite" and 50% sansamp sound, just on the edge of valvey breakup when I dig in, but not too scooped.
Sounds awesome. These are the best live basses for me, as they cut through every time.
But at home I prefer a subtler sound, more refined and "hifi" if you like.
But for live use I don't think a Stingray can be bettered - I am always confident that my sound will be just what I need it to be.
My SR5 cost £800, and SR4 £700, both bought used on here.
Re the weak G string thing, mine is slightly down on the SR4 (not on the 5), but not enough to bother me in the slightest.
What would I change? - the SR5 is heavy, that is all.
