New Supro USA Dual Tone Tube Combo Amp 1624T 4-watt 1x12" Tremelo

The “Dual-Tone” 1×12 combo amplifier is the undeniable rockstar of the mid 60’s Supro amplifier lineup. Vintage 1624T amps have beensought-after for decades because they embody the most desirable aspects of theSupro sound. As the Dual-Tone’s volume knob is turned beyond noon, a fat andcompressed clean tone evolves into an immediately recognizable grind thatremains articulate and listenable even when turned up to full blast.

This 24-Watt, 1×12 tube combo can easily be driven toglorious saturation at a manageable gigging volume while retaining exceptionalclarity and bandwidth, at any level of gain. This amp’s unique mojo is largelydefined by the use of 6973 power tubes in the amplifier’s output stage. Theserobust 9-pin tubes were employed extensively in the mid- and low-power Suproamps made 50 years ago. 6973 tubes look like EL84s but they deliver adistinctly American voice that has been missing from the world of tubeamplifiers for far too long.

The Dual-Tone’s linkable channels each sport volumeand tone controls as well as a shared tremolo circuit. Plugging into IN 1+2links both preamp channels in parallel for double the input signal and doublethe gain. This clever topology lets you hit the power amp as hard as necessaryand even allows “channel switching” in its purest form, using a simple A/Bswitch.

The 1964 reissue Supro Dual-Tone’s vintage-correct,lightweight cabinet—combined with the breathtaking custom 12” Suprospeaker—kicks out surprisingly plump low end with all the detailed midrange andhigh end articulation that defines the Supro tone players have been chasing fordecades. Loud enough to gig with a band, yet easy to haul around town, theSupro Dual-Tone is the perfect small club and recording amplifier. This amp hasthe long lost tone.
