I'm looking at a great deal on a DC-5 but don't know the subtleties of them. I've owned a DC-2 and wasn't so impressed but really want a 6L6 amp and the DC-2 also didn't have the GEQ like this one does. One difference I saw is the one I'm looking at has a silver toggle switch on the back and others I've seen have a rotary knob to choose footswitch options. Can you help me out? Thanks!
