I'm looking to buy a small tube amp for home/rehearsals/gigs. Just can't deal with lugging around a 2x12 cab and a separate head every week when I don't need the volume. So far I've narrowed it down to a Pro Junior and a Silverface Champ. I realize the two amps are completely different animals, and I'm leaning towards the Pro Junior for its lead/bite sound. However, there are a couple local deals going on, including a super champ as well as a vintage Bronco. What's the difference between the vintage super and vibro champs (also known as the Bronco)? The champs seem to do cleans really well, but how well do they overdrive? I'm mainly afraid of sounding too ice-pickey as I can hit notes hard when playing leads.
