Supro Black Magick head with two matching 1x12 Black Magick cabinets Guitar Amplifiers, (Used)

The Supro Black Magick head with two matching 1x12 Black Magick cabinets is a valve amplifier and speaker system designed as a recreation of a late-1950s Supro circuit associated with early rock recordings. The head is a 25-watt Class A all-tube amplifier using a pair of 6973 power tubes and multiple 12AX7 preamp valves, built to deliver high gain and dynamic response. It is housed in a compact head enclosure and designed to be paired with external speaker cabinets, forming a modular amplification system.

The amplifier features two parallel preamp channels with independent volume controls and a shared tone control, allowing the channels to be used separately or linked together through the input configuration for increased gain. It includes a built-in power tube tremolo circuit, which modulates the output stage to create amplitude variation, and operates without a master volume in its standard form. The circuit design is based on vintage Supro topology, enabling a range of output levels and tonal variation controlled primarily through input gain and instrument dynamics.

The matching Black Magick 1x12 cabinets are extension speaker enclosures fitted with a single 12-inch Supro BD12 speaker, designed to complement the head’s output characteristics. Using two cabinets allows for increased sound dispersion and projection compared to a single enclosure, while maintaining the same tonal voicing across both speakers. The cabinets are finished in matching black tolex with a silver/black grille cloth, forming a unified amplifier system intended for use in stage or studio environments.
