I'd be very interested in hearing how you think the sb compares to your old cornford (and which one?).
I am considering to buy my old mk50 ii back or go for the small box.
I know my mk50 ii had the open and raw tone that I desire, but it felt a little stiff at times and the gain structure was not as rich as good marshalls usually are. However, the leas tone was so fat and powerfull .. The amp has so much balls , huge but always controlled bottom end with tons of punch. Anf I fear that the sb maybe cannot match properties (will sound smaller, weaker or more compressed).
Hope to hear your assesment ... At the moment i am swaying to the cornford , but would hate to miss out on the sb - btw it is not possible to try a friedman before buying.
