Precision, Power, and Tone!

When asked, by Corky James, amongest others, "Can you take my favorite 1959 tweed amp from Fullerton and instead of the controls being Volume Volume Tone make it Volume Treble Bass, give it more clean headroom, a wider range of usable overdrive (throw in a little EL 34), make it a little louder with fuller, tighter low end, and put a master volume in it so i can play at all levels and dial in and hit the sweet spot of whatever speaker i am using at the time, mostly a G12M Celestion?"

Divided by 13 obliged with the CJ 11 1x12 combo.

The Divided by 13 CJ 11 delivers 11 watts of Class A combo amp power driven by a pair of 6V6 output tubes. This is a tube rectified powerhouse with a single channel and simple Volume, Treble, Bass, and Master Volume controls. The Divided by 13 CJ 11 can reproduce any tone from sparkling clean to blistering lead at any volume for any situation. Perfect for both the stage and studio, the Divided by Thirteen 3 CJ 11 has a crisp, clear tone that saturates extremely well and has a very balanced sound across the frequency spectrum. The Celestion G12M Greenback really brings out the top end and high mids for a focused sound and the low wattage of the cone is perfect for adding some speaker distortion. Well dressed in garnet and egg colored tolex for a stunning look that is as great as its sound, the Divided by 13 CJ 11 is the perfect amplifier for rock, blues, or country.

Drawing from the iconic 50’s era 1×12 tweed combo from Fullerton that created the quintessential “American” guitar sound, the CJ 11 elevates this classic with enhanced tone shaping, mid/gain pull boost circuit, improved output performance, and the addition of a master volume, all while maintaining the original design’s signature appeal.  

In contrast to the original’s setup of a single tone knob and dual inputs with individual volume controls, the CJ 11 features a single channel equipped with both Treble and Bass filters, along with a Master Volume. The addition of a Bass control enables the reduction of lower frequencies when the amplifier is pushed into saturation, avoiding the muddiness and compression typical of earlier designs. However, when desired, the classic low-end response and heavy compression that define the vintage circuit are preserved at higher bass settings. With the addition of a Master Volume, the CJ 11 can deliver a range of drive tones, from a subtle edge of breakup to moderate overdrive and full “tweed-style” saturation, enhanced by the onboard boost, all at more controllable volumes than vintage models.

The CJ 11 power amp maintains the classic dual 6V6 power tube complement while upgrading the rectifier from a 5Y3 to a more robust 5AR4/GZ34. Along with an augmented power supply and custom-built transformers, this design delivers enhanced headroom, louder output, improved low-end clarity, and a broader spectrum of usable overdrive.  

Although the CJ 11 builds on a classic ’50s design with thoughtful updates informed by years of experience, it preserves the essence of what made the original exceptional while offering greater versatility. With its 1×12 cabinet and a Celestion G12H speaker, the CJ 11 remains portable yet delivers performance that far exceeds what its 11 watt power rating suggests.
