The Fullerton™ is our vastly expanded take on the most recorded small 6V6 amp in history! We took the stock platform of the Princeton Reverb, doubled the power to 40W, added a 3-knob Reverb.

If the Princeton Reverb has one complaint, it is that it is not powerful enough to remain clean at loud stage volumes. With this in mind we opted to double the number of 6V6 output tubes in the Fullerton from 2 to 4, and in so doing doubled the maximum power of the Fullerton to 40W! This increased power, along with our custom wound 200W output transformer, will deliver more volume, headroom and low end punch than you’ve ever heard from a Princeton Reverb! Low notes that typically can “flub out” on a Princeton will remain crisp, tight and focused as the extra wattage works to deliver your tone with unparalleled clarity and definition. We have also included a Half Power Switch on the back of the amplifier so you can adjust the output power from 40W down to 20W. 


The Open Back 1×12 Cabinet from Jackson Ampworks is a perfect speaker cabinet to complement our entire line of amps and is ideal when you want a tone that is more “airy” and fills out the musical space! Designed while the American Series amps were being developed, the Open Back 1×12 Cabinet gives you the sense that your tone is coming from every direction and surrounding you as the open back design allows the tone to emanate from both the front and back of the cabinet!
