Divided by 13 CCC 9/15 Review

D13’s history is not unlike Two-Rock’s. But the two companies are known for very different sounding amplifiers and very different designs. As it happens, the contrast makes the current Two-Rock company—itself purchased by long-time team members Eli Lester and Mac Skinner in 2016—a complementary new home for D13. The revived CCC 9/15 model, tested here, is from the smaller end of the reanimated range. Although, as we’ll discover, there’s little that’s truly “small” about any amp wearing the D13 badge—at least sound-wise.

Double Duty

Based on Taccone’s acclaimed dual-output-stage design, the CCC 9/15 delivers around 9 watts from a pair of 6V6GT tubes in class A mode, or 15 watts from a pair of EL84s in class AB1 mode (both configurations are cathode-biased). It’s all housed in a stylishly appointed cabinet covered in two-tone burgundy and ivory—together in perfect harmony—with the traditional D13 “widow’s peak” on a top-front panel framing an illuminated “÷13” logo plate. Measuring 22" x 211/4" x 10.5" and weighing 48 pounds, it’s chunky for a 1x12 combo of relatively diminutive wattage. But as Taccone would say, “There’s no big tone from small cabs,” and the bigging-up continues right through the rest of the design.

With a preamp stage that’s kin to the D13 CJ11, the front end of the CCC 9/15 is a little like a modified tweed Fender design. Driven by two 12AX7 twin triodes, it’s not a mile from the hallowed 5E3 Fender Deluxe, but with an EQ stage expanded to independent bass and treble knobs. Apart from those, there are volume and master volume controls with a push-pull gain/mid boost function on the former. In addition to the power and standby switches, there’s a third toggle to select between EL84 and 6V6 output, with high and low inputs at the other end of the panel. Along with two fuse sockets and an IEC power-cord receptacle, the panel on the underside of the chassis is home to four speaker-output jacks—one each for 4 ohms and 16 ohms and two for 8 ohms—plus a switch for the internal fan, acknowledging that all those output tubes can get a little toasty after a while.

“Set to 6V6 mode, the CCC 9/15 exudes ’50s-era tweed warmth and richness, with juicy compression that feels delightful under the fingertips.”

The combo cabinet is ruggedly built from Baltic birch ply and houses a Celestion G12H Creamback speaker. Construction inside is just as top notch, employing high-quality components hand-soldered into position and custom-made transformers designed to alternately handle the needs of two different sets of output tubes. In a conversation I had with Taccone several years ago discussing the original design, he noted that by supplying both sets of tubes with identical B+ levels of around 300 volts DC (courtesy of a 5AR4/GZ34 tube rectifier), the EL84s ran right in their wheelhouse—producing around 15 watts, and probably more, in cathode-biased class AB1. The 6V6s operate less efficiently, however, and can be biased hot to true class A levels, yielding just 9 to 11 watts.

Transatlantic Tone Service

Tested with a Gibson ES-355 and a Fender Telecaster, the CCC 9/15 delivers many surprises in spite of its simple controls and is toothsome and dynamic throughout its range. Between the four knobs, push-pull boost function, and 6V6/EL84 switch, the CCC 9/15 range of clean-to-grind settings is impressive regardless of volume, short of truly bedroom levels, perhaps. It also has impressive headroom and a big, robust voice for a combo that maxes out at 15 watts. Leaving the boost switch off affords the most undistorted range from the amp in either output-tube mode, though the front end will still start to push things into sweet edge-of-breakup with the volume up around 1 or 2 o’clock. Pull up that knob and kick in the boost, though, and things get thick and gutsy pretty quick.

While the power disparity between the 6V6 and EL84 settings is noticeable in the amp’s perceived output, which enhances its usefulness in different performance settings, you can also think of the function as an “era and origins” switch. Set to 6V6 mode, the CCC 9/15 exudes ’50s-era tweed warmth and richness, with juicy compression that feels delightful under the fingertips. The EL84 setting, on the other hand, ushers in ’60s-influenced voices with familiar British chime, sparkle, and a little more punch and cutting power, too.

The Verdict

If the CCC 9/15 were split into different 6V6 and EL84 amps, I’d hate to have to choose between them. Both of the amp’s tube modes offer expressive dynamics and tasty tones that make it adaptable to all kinds of venues and recording situations. From the pure, multi-dimensional tone to the surprisingly versatile and simple control set to the top-flight build quality, the CCC 9/15 is a pro-grade combo that touch-conscious players will love. It’s heavy for an amp in its power range, and certainly expensive, but the sounds and craft involved will make the cost worth it for a lot of players interested in consolidating amp collections.
