The Black Magick Reverb Head embodies the all-tube snarl and sweetness that define the Supro sound. Featuring analog spring reverb, 2-band EQ, and a master volume knob, the Black Magick Reverb was designed with maximum flexibility in mind. Two independent preamp channels can be linked together using the "1 + 2" input jack to obtain fat tone, while utilizing only Input 2 will yield a more agile sound. The Black Magick Reverb's 3-spring reverb pan is driven by both channels and then summed with the dry signal just before the master volume control. An updated, tube-based LFO circuit provides bias-modulated output tube tremolo with double the speed range of the original Black Magick.
