I had an original Tverb back in the mid to late 1990's that I loved. Over the years however I have become a Marshall'ish guy through and through. I did like some of the riffs that you played better on the DR though.
What boost are you using? Doesn't look like you are running the gain on the 800 very high and my 2203X does not have that much gain on tap even with a boost.
