Description
Meet the Seymour Duncan PowerStage 700, a game-changing power amplifier designed specifically for guitarists who crave uncompromising tone in a compact package. This power amp offers a solution for musicians who love their tube amp but dislike the burden of its weight. It's ideal for those who use a modeler with plenty of functionality but lackluster sound when connected to an existing amp or directly to the PA. The PowerStage 700 is perfect for those with an ultimate pedalboard looking for a superior way to amplify it or run it directly.
The PowerStage 700 is a versatile companion for the current generation of amp modelers and effects processors. It takes your carefully crafted amp sounds and reproduces them in detailed fashion, offering power, clarity, and a warmth that elevates even the most advanced modeled tones to the next level. Thanks to the True Cab Circuitry (TCC) on the XLR line outputs, you can send your tone directly to the front of house, maintaining all the feel and response of a speaker, even while you monitor through a cabinet onstage.
This power amp also offers a musically voiced 3-band EQ, allowing you to fine-tune your sound quickly and with precision. It's the missing link in your signal chain, amplifying your perfect tone in a clean and toneful way. The PowerStage 700 is not just for live gigs; it can be your secret weapon in the studio, solving all your impedance issues, and allowing you to run your pedals straight into your DAW.

"The Seymour Duncan PowerStage 700 is the first power amp, in my experience, that's designed specifically for the guitar player"
"Immediately the first thing i noticed was that i had tons of flexibility, for instance, if i didn't like the way a room sounded, if it was sounding particularly dark or particularly bright i knew that i had the ability to just reach over and have an extra level of tweakability right at my fingertips, and i didn't have to go into my modeler and start tweaking amp settings or pedal settings, i could just go and start tweaking the settings on the 700"
