Thanks for the help. Still don't understand how my manual says 8s but I've changed to 10s and love it.
Glad to hear the 10's went on well and your guitar sounds good. If you stick to the same gauge strings ( 10's are the best for most) you will seldom have to do a truss rod adjustment and if you do it will only be minimal during a seasonal change.
If you ever do a rod adjustment, it is best to use the correct Rickenbacker tool, which is long and straight. Note other types of truss rod tools can damage your guitars truss rods.
