To be accurate, your best chance is to contact Peavy about the Wolfgang guitars, but I think in 97 it was introduced to the namm show and was available to the market the following year. EVH left MM in 95.
Hope this helps Jim, wish I was more knowledgeable regarding Peavy, but my expertise is with EBMM.
