Forgetting the B string is there until needing to play across or treating it like a thumb-rest in my opinion might not be the best approach to incorporating it into your playing. I suggest using it immediately and often. My mental anchor was the 5th fret of the B string being the same as open E string-that way the 5 notes I played below that was what separated it tonally from a 4-string. @NickA I have never heard the B string on a Stingray being described as weak before. All the ones I owned in the past would disagree with that and don't get me started on my two Warwicks and my Marusczcyk fivers,all 34" scale. I don't personally buy into the 35" for a better B based on my personal experience but I'm digressing now🙂
