Thanks Linnin, we always take a chance going by web recommendations and new tech so it's great when it turns out it lives up to expectations. I have been totally satisfied with my Rumble gear, and honestly, the sound is right in the ballpark of the SVT I had and the LAB4 230 W SS head I had (which is now broken, but I would like to get it fixed). Don't get me wrong, I never drove the MIGHTY SVT too far because the pain was too great to bear, but the Rumble, to me, delivers the a similar sound as both the SVT and the LAB4 Solid state. And also I don't want to push it to the limit. You know, hearing and all. But the tone is right up there with the greats. Viva La Rumble.
