Cool, tiny little amp, Sovtek MIG-50H. The high gain version of the MIG-50. As if the MIG-50 was not already a very small amp this is squashed together and is even smaller. Looks like the knobs have been replaced with Marshall-style ones on this piece.
Actually a nicer build in this MIG-50H compared to the MIG-50 I’d say because it has actual traditional style 1/4″ solder lug pots for the volume and tone controls that are attached to the front panel and are much sturdier than the crappy plastic PCB mount 1/8″ pots in the MIG-50 that always break and then you need to buy new knobs too. Wonder if that’s original or if a previous tech installed those. Definitely a step up.
This MIG-50H has metal on/off and standby switches too, nice.
