Hello All, I just got my new D13 23. I have to say that I am actually overwhelmed with how good this amp actually is. It is like the best metal panel 71 Marshall, and the best Park 75 that I ever had rolled into one unit with something a little extra in there as well. Very touch sensitive and responds so lightening fast that it is unbelievable. It does its own thing but covers all of my Brit rock amp needs and then some. I am running it through a late 60's Marshall cab that I loaded with a set of Blues... Man oh Man, I can't say enough good things about this amp. Yikes!
