    An Update On An American Classic

    Exactly 50 years after the release of the Princeton Reverb, Jackson Ampworks has created their own take on the 6V6 powered, American-voiced amplifier. Dubbed the Fullerton, the resulting amp pays homage to the Fender classic by utilizing what has made the amplifier a studio workhorse for over five decades; reverb, tremolo and incredible tone.

    Doubling Up On Power

    When looking to build upon the original amp design, the minds behind Jackson Ampworks set out to solve the issue of creating clean tones at a loud volume. The Fullerton achieves this by doubling up on 6V6 output transformers, now using four tubes instead of the standard two. By increasing the amp’s output to 40W, Jackson has ensured that the Fullerton is capable of pushing more volume with undeniable punch and maximum headroom.

    The Reinvention of Reverb

    From subtle to surfy, Jackson Ampworks has improved upon the single knob reverb system by building a three knob, tube driven spring reverb into the Fullerton. These controls feature a Reverb Send, Reverb Tone and Reverb Return, which allows for you to decide how hard the reverb is driven, the warmth/brightness of your tone and the amount of signal that goes back into your dry mix.  

    Controlling Your Tone

    Forgoing the traditional Treble and Bass controls, the Fullerton opts for a three-band EQ with knobs for Treble, Middle and Bass. The amp achieves the Princeton Reverb sound when the Middle control is set to the 12:00 position, but allows for tonal experiments when boosting and cutting mid frequencies depending on which way you turn the knob.

    For those familiar with amplifiers that feature a bright switch, you likely have experienced an amp that may be too dark when the feature is not engaged. To prevent this issue with the Fullerton, Jackson Ampworks has wired in a permanent bright cap and installed a master control to create a wide range of tones from extremely bright to incredibly dark.

    In addition to the basic controls and bright cap, the Fullerton also features a new Tweed control, which enables the amp to get back any gain lost while traveling through the EQ controls. At 0, the amp offers up the classic, clean sound that is typical of an American classic like the Princeton Reverb. When the Tweed knob is cranked, you’ll get more preamp gain added to your tone and a hearty boost.
