Just wanted to add, I have the Origin 20 Combo and the DSL 20CR. I find the DSL20 has either not enough gain on the clean channel or WAY too much on the dirty. So don't do what I did and be tempted by the DSL 20. My plan is to sell both and get the SV20 and figure out an affordable way to attenuate it. Im hoping for the Boss TAE but between the both of them its a $4k purchase (i.e. NOT affordable).. The SV20 appears to cover most of the ground you are talking about. The SC20 seems a bit thin on the Classic Rock sound.
