The universal guitar stompbox power supply Powerbox Mk2 is built in a compact metal
box which measures 13х5х10 cm. The construction has been repeatedly optimised with the aim
of using internal space most efficiently so the dimensions could be as small as possible, without
compromise in quality. Powerbox Mk2’s heart is a high-quality transformer with a reduced flux
density, which guarantees reliable operation. In addition, the device has been designed with 5
galvanically split groups, each of them supplied with independent electronics for rectifying,
filtering and stabilizing the current. In this way the typical adapter-powered ground loop
problems are drastically reduced to achieve very low levels of noise. Each group is fitted with
its own control LED, situated between the two out connectors. It indicates the presence of
outgoing current.
