The “Dual-Tone” 1×12 combo amplifier is the undeniable rock star of
the mid 60’s Supro amplifier lineup. Vintage 1624T amps have been
sought-after for decades because they embody the most desirable aspects
of the Supro sound. As the Dual-Tone’s volume knob is turned beyond
noon, a fat and compressed clean tone evolves into an immediately
recognizable grind that remains articulate and listenable even when
turned up to full blast.
This 24-Watt, 1×12 tube combo can easily be driven to glorious
saturation at a manageable gigging volume while retaining exceptional
clarity and bandwidth, at any level of gain. This amp’s unique mojo is
largely defined by the use of 6973 power tubes in the
amplifier’s output stage. These robust 9-pin tubes were employed
extensively in the mid- and low-power Supro amps made 50 years ago. 6973
tubes look like EL84s but they deliver a distinctly American voice that
has been missing from the world of tube amplifiers for far too long.
The Dual-Tone’s linkable channels each sport volume
and tone controls as well as a shared tremolo circuit. Plugging into IN
1+2 links both preamp channels in parallel for double the input signal
and double the gain. This clever topology lets you hit the power amp as
hard as necessary and even allows “channel switching” in its purest
form, using a simple A/B switch.
The 1964 reissue Supro Dual-Tone’s vintage-correct, lightweight
cabinet—combined with our breathtaking custom 12” Supro speaker—kicks
out surprisingly plump low end with all the detailed midrange and high
end articulation that defines the Supro tone players have been chasing
for decades. Loud enough to gig with a band, yet easy to haul around
town, the Supro Dual-Tone is the perfect small club and recording
amplifier. This amp has the long lost tone, so Ramble On down to a Supro
dealer near you and Bring It on Home.
