I recently bought a used (like new) Peavey 210 TVX cab. I noticed when I got it home, the speakers had a blue tint. Curiousity got the best of me and I popped a speaker out and it turns out the previous owner must have replaced the Sheffields (Peavey stock speaker) with Eminence Gammas. Normally I would let the sound be the judge, but it could be awhile before this bottom gets gigged and gets a good workout. Should I be happy or not? Anyone have any opinions/experience with the Eminence Gammas?
