Well, for those who were asking, I did get to put the Whappo, Jr. through its paces this weekend, and it pretty much confirmed my expectations. Mark has definitely met his design goal of a single box that can replace two (or more!) larger cabs. Volume-wise, it did as well as my Mesa Boogie 4x10/Eden 212XLT rig ever did. The sound that your hear when it is quiet (full, balanced sound) stays consistent as you crank it. At first, I thought to myself that it was a bit laid back in the mids, but then I realized that it was just so darn full-sounding. The mids are all there, and cut through just as you would want them to. But you also have excellent low end, which shines through whether you are thumping on a low B, or if you are playing further up the neck. You pretty much always have a nice, thick tone - not just when you are playing on the bottom two strings. And don't think that this will muddy-up the mids. It doesn't. They cut through just fine. I will say that the high end is not as bright as with my EA or Epifani cabs. I know that Mark is obsesses with "No Hiss!", so his tweeters aren't as in your face as some others. However, if you want to hear a little bit more high end, a simple EQ nudge, and there you go. And guess what? Still no hiss!
Call me a happy camper. I may, however, still bring a second cab to set on top of my rack to get a bit more going on at ear level (when I have to stand fairly close to my rig). But there certainly is no
need to bring a second cab with the Whappo, Jr.
Later, Tom.
