That's how mesa used to do the bottom cabs. (straight cab with slant baffle) Now the straight cabs have a straight baffle.
Bryan, I had a straight Mesa Stiletto cab with a straight baffle. What I did not like about it was that the baffle was perfectly straight with the front of the cab, and not angled up slightly like a Marshall straight cab would be. Therefore, the sound was directed at your knees instead of at ear-level when standing in front of it. You'd have to squat down to really hear how bright your tone settings were. When I sold it and bought my oversized cab, I got the angled one for this reason. Just something to consider... In terms of Marshall cabs, I prefer bottom/straight cabs. For Mesa cabs, I prefer the angled cabs.
