When i had a '69er, it was a great cab, but my preferences were moving towards very deep and very clean, and it was adding too much colour for that. Enter the Super Twin, and I'm over the moon with it. I have a very, very powerful poweramp, and even when I crank it as loud as I dare (about half way) the Super Twin can handle it, staying ultra clean, clear and defined. Superb cab ☺
