Once I let a moron plug into my Fender Bandmaster cabinet, which I used a Carvin P-5000 brain, in which we already blew out the Jensens, and replaced them with Pyle Drivers. He fried both speakers, cranking his 'overdrive' up, way to high. That really pissed me off, but in actuality was fortuitous, because I replaced those(Pylie Drivers) with Carvin High Energy 12's. Now it is incredible!..and indestructible! Sounds better than ever!.....but try to plug into it???..ummm, no morons allowed! You can tell a moron, because they laugh like, 'Guh huh, Guh huh'!!
