I think that sort of thing just takes time. I started out on a 32" scale bass. when I go back to my current 32 I feel like superman lol. just so easy to get around. took me quite a while to get used to 34" and 35". my hands, despite being very large... get stretched and soar still when playing 35". If you don't have side dots (does an sg bass have side dots?)... that might help - it's all I look at anyway. Perhaps try to practice more with your eyes closed.
