Early on, Ed used Fender 150 .009 strings that were 9-40. I used the same ones, too. That’s why those early 5150 strings were the same gauge.
Funny... I ultimately ended up playing the Fender 150XLs after the 5150s as I preferred the pure nickel and I couldn't find others in that gauge.
I used them for probably 20 years until they stopped making them and I couldn't find them anywhere.
Now I use the 9-42 Fender Super 250 strings.
