The “Dual-Tone” 1x12 combo amplifier is the undeniable rock star of the mid-'60s 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, 1x12 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.

    Comments about Supro 1624T Dual-Tone 24W 1x12 Tube Guitar Combo Amp:

    I ordered one of these as soon as I learned Supro was producing them. There were no units in unopened boxes available across the Guitar Center network so I had to settle for a demo. The first one I received came with a fried tube and non-functional second channel. I returned (graciously and apologetically received by the GC staff) it and ordered a second. This one came with damaged Tolex, which I was able to easily repair, however it was electronically intact. Beautiful amp with great sound that better complements Fender single coil pickups rather than Gibson humbuckers. This amp adds a gutsy bass and midrange to my Strats that no Fender amp has ever been capable of. Works well with overdrive pedals. One caveat, while you can overdrive the amp by plugging into channel (1&2), it is so loud that it's unusable in a small gig just beware! Otherwise, I highly recommend this amp if you are a fellow Strat slinger.

    Comments about Supro 1624T Dual-Tone 24W 1x12 Tube Guitar Combo Amp:

    24 Watts? Are you kiddin' me??? This thing is 24 bucketfuls of Badassery! I have used a ton of different Fender amps down through the years. This thing totally kills them all with the possible exception of that chimey clean sound that Fender does so well. On everything else, from warm fuzz all the way to dimed out wailing grit, the Dual Tone completely satisfies in a way that Fender NEVER could.
    My Tube Screamer and Rat pedals are collecting dust because I can get everything I need just plugging straight into the amp. Before this, my fave studio amp was a modded Fender Blues Jr. That amp is now for sale. The Supro costs twice as much as a Blues Jr and it's worth every penny.
