Right.
Pro, then semi pro bass player. Walked into my 1st session in 1987 aged 17, still recoding and playing live now.
I worked my way through a bunch of brands and settled on these.
I used Rotosound, Dean Markley, Ernie Ball, I cant remember what else and the found these in the mid 90's.
I find them to be really reliable & consistent, bright yet deep, tight & full.
I like the consistent gap between them in gauge, i.e always .2
I match the gauge of stings up to the thickness of each neck - Precisions & Jazz's usually 105- 45's & Ibanez/ESP et al. 100's - 40's. This will vary a little bit.
It's just how I do it, no idea about others.
I try other stings as they come along but always come back to these and now I have been using them for coming on 30yrs. They are defiantly are part of the sound that I am paid to produce (which is still amazing to me), and I have a lot to thank them for.
The only time I move away is for flat wounds.
