Vox Nutube Head, 50 watts with cab - $235 (Florence)

The MV 50 High Gain head is a hybrid tube amp, with Nutube technology.
Sells with a cabinet, the BC108 has been specifically voiced to push a deceptive amount of low end and punch from its diminutive size.
And the cabinet's semi-open back design offers a wide sound dispersion while simultaneously retaining a tightness in the lows that is rare for micro enclosures.
