That's really interesting. I've never found a Jensen that I cared much for (I know, I know), but the MOD series seems to be something different. Unfortunately, as I was cruising their website, I noticed that all of their sound clips are the same clips for every speaker. I'll see what I can find on YouTube.
I don't know what you're looking for as far as tone. I liked the MOD better than the stock 50 watt Alltone speaker that Reverend put in it. The Alltone was under ratted, why would they put a 50 watt speaker in a 60 watt amp? I couldn't get a good clean sound out of it, too much break up at normal gig volume, not blowing down the walls. Some guys like it that way so I sold the Alltone (cheap) and tried the MOD, never tried one before. Since then I've put them in 4 other amps. Ones I fixed and sold, nobody has complained about them yet. So I guess they must like it okay.
