NBD Carvin AC50

Just got this in a trade for an Avatar cabinet. It's a fretted 5 string,to compliment my AC40 Fretless. It came with a new set of Rotosound tapewounds,which appear to be too big for the nut slots. (the d string is the only string sitting IN the slot,the others are almost completely on top of the nut). Even though i love the Labella tapes on my fretless,the Roto's sound clacky and kind of warbly on this bass. Anyone try any other string types on their fretted ac40/50's? This is actually the first 5 string bass I've ever owned,so there is going to be a learning phase of seeing if i can get accustomed to playing it. It has one of the most comfortable (wide and shallow) necks i've played,and the feel overall is great. I am really impressed by Carvin's build quality and well designed details.

 

The Roto trubass set is 65-135,with a 115 E,pretty much the same as the Labella set,so i don't know. The wrap on the rotos is a lot bigger and looser looking than the labellas on my fretless. I have ordered a new set of the Labella white tapewounds for the 5 string. I will probably try to sell the rotos,since they are brand new. I have not used or liked any rotosound strings in decades now,and it looks like these are not going to change my mind about them. The nut looks original to me,so if the new labellas don't fit in the slots,i will file them a bit. I was thinking about puting flatwounds or even half rounds on the bass,but i think the labella's are a great sonic match for these basses.
Meanwhile,here's another pic of the back of the bass. The trans green looks really nice over the mahogoney,doesn't it?
