Any other ultra light string users here?
I tend to favour Rotosound. Occasionally I'll try another brand but I always end up going back. Can't say I've noticed a tonal difference with lighter strings, and they suit my playing better as I like to use ramps.
I need my ultra lights to be long scale, because even though my Shuker's are medium scale, I have the extended fretboard on my E string (for a low D).
