I guess they are quite similar with vc 30 except the 30 has more horsepower under bonnet:
i have the twice smaller vc15 with 8ohm RI jensen C10Q and i´d say it is a really damn good amp, i am very pleased with it. No issues within 1.5 years. Clean is nice and the crunchy overdrive delivers easily some heavy/hard rock , i guess something like vox. the vc15 sounds surprisingly good also on low volume, even in drive channel. Reverb is better on lower volumes, high volumed and max dialed it can get a little ´spongy rubber´
(Meanwhille i was thinking of buying the
GS112VE under it but it seems there´s
no point , better to keep eye on some used peavey classic 50 for bigger sound for me)
so, i´d buy that vc-30 , especially if it´s good priced.
