Hi mate, good to hear you had a trip up to God's own country with a lovely lady friend. No doubt you will be cheering for the maroons tomorrow night?
Looking at the photo of this axe it looks like a volume only job and either pot will do but would suggest trying the 'A' one first as that has a gentler roll off than a 'B'.
Suggest having a look at wiring diagrams for a LP Jnr as they only have one single coil PUP and you could ignore the tone control perhaps...refer below link where you would ignore the tone pot and just run the earths off the back of the Vol pot. You could also experiment with running a capacitor like on the tone pot on the vol pot instead to see what that does. If you don't like it you could always snip it off.
Cheers, Waz
