From the manufacturer: THE PORTABLE HOLY GRAIL AMP The Black Magick head is a faithful recreation of one of Rock n' Roll's holy grail amplifiers. Its circuitry, build and cosmetics are modeled after Jimmy Page's beloved 1959 Supro combo, famous for offering most of the tones heard on Led Zeppelin I. A 25-watt, Class A, all-tube amplifier, the Black Magick offers more gain than any other Supro amp. Its 6973 tubes offer the instantly recognizable midrange grind and phenomenal touch dynamics that define the Supro sound. 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. Our signature power tube tremolo adds footswitchable depth and dimension to this Rock n' Roll time machine. Also available in combo format. ALL-TUBE SENSITIVITY AND SNARL Class A power amp utilizing a matched pair of 6973 tubes and a custom-made Supro output transformer with 16-ohm, 8-ohm and 4-ohm output options. Phenomenal touch sensitivity and bite. PREMIUM LOOK AND FEEL Our custom Black Rhino Hide tolex, Supro Silver/Black grill cloth, white welting, and our custom Supro Arrow design on the head cabinet create premium feel and lifelong durability.
