The Supro Jupiter is a modern masterpiece. This top-of-the-line Supro
amp is intended for the performing guitarist who needs a vintage
sounding amp that gracefully handles the output from a complex pedal
rig. The Jupiter amplifier excels at rock, funk, fusion, jazz and
electronic music genres, providing the necessary headroom punch and
stage volume without sacrificing the fundamental dynamics and tonal
characteristics that have made Supro amps famous.
The Jupiter model features our unique switchable rectifier topology,
allowing musicians to select 35-Watts (Class A) or 45 / 60 watts (Class
AB) to suit the gig at hand. The 35 watt cathode bias mode uses the
legendary Thunderbolt power amp topology for a harmonically saturated,
tube-rectified sound that combines wonderfully with this 1×12” platform.
The 45 and 60 watt grid bias modes provide more volume and headroom as
well as the faster transient response associated with Class AB power
amps.
The switchable power amp topology of the Jupiter not only allows for players to change the texture and
output volume of the amp but it also provides two very different,
all-tube tremolo effects depending on whether Class A (cathode bias) or
Class AB (grid bias) mode is selected. The cathode bias tremolo is
vintage Valco/Supro all the way, where the overall depth of the effect
changes along with the dynamics of your playing. The grid bias tremolo
is gives a much deeper, stronger and more pronounced throbbing effect.
Since the tremolo is performed by modulating the bias of the output
tubes, the reverb necessarily comes before the tremolo effect, for a
mesmerizing combination of pure tube reverb and tremolo when both
effects are combined.
The Jupiter amp comes equipped with a brand-new, state of the art,
USA made HP12 speaker that was designed specifically for this model. The
HP12 speaker is a unique driver that combines the exceptional clarity
and treble extension of the Supro DT12 speaker, with superior power
handling due to a larger magnet and a hemp cone. This speaker’s
distinctively smooth character remains sweet, no matter how hard you
push it, delivering a full bodied woody tone has no equal in the world
of guitar speakers.
