I have the Jensen C12N in an Alessandro Working Dog, and it sounds great clean, but it gets a little nasal and pinched sounding when I drive it hard for leads. I was thinking about replacing it with one of the Reverend Alltone 1250's, but aren't they based on the Jensen? If so, then I would think I'd just be getting more of the same. Anybody compared these two or have experience with the Alltone?
