When Peavey first started building the Wolfie, they were using National Strings(Mapes, Black Diamond)...they eventually went to D'Addarios(standard nickel wrap).
In order of mellow to brighter tone: nickel, nickel plated steel, stainless. As Lisa stated, any brand of string will work just fine but you may need to adjust for minor differences regarding intonation and core wire/wrap wire ratio.
