The Dokken tone, or maybe more the playing, was on point in that clip.
I had and enjoyed the SC20. I've read people's posts saying it's too loud, or that it doesn't hang with the big watters.
It's not too loud, at all. If you can't get a decent tone out of it at house volumes, it's your fault. It sounds like a good JCM, but a 20w version, meaning more mids, less low and highs and volume than a 50w/100w. It still rocks.
I wanted to buy the Sv20 the first time I played it. I've had 7 4 holers, and it sounds like a good one. Don't care for the build quality, but for $800-$1g used, it's OK. Build wise, it's no Germino, Suhr, Metropoulos, Ceriatone, Rockett...
But it brings that sound at a lower volume, at a good price and in a small package.
