The Seymour Duncan PowerStage 700 is the most powerful of the US company's power amps – packed into a pedalboard-friendly format. It's been designed specifically for guitarists who create their sounds entirely through pedalboards, multi-effects, or modelling systems, so it's for anyone who needs neutral, high-powered amplification for their speaker cabinets. Thanks to 700W output at 4 ohms (350W at 8 ohms), the PowerStage 700 can drive even large 4x12 cabs or full-range speakers. An integrated fan ensures reliable heat dissipation, while the convenient built-in power supply circuitry reduces clutter, as there's no need for an external power brick. Two switchable cab-sim outputs and a three-band EQ provide flexible signal options for FOH or recording – all housed in a rugged, American-made enclosure.
The control panel of the Seymour Duncan PowerStage 700 is clearly laid out: Dials for volume, bass, mid, and treble allow musicians to make minute adjustments, with up to 13dB of boost or cut available in each frequency band. The speaker simulation can be switched separately for each XLR output, making it ideal when the sound techs need different signals at FOH and on the monitors. The front of the device houses the two 6.3mm mono inputs (L/R), while the rear features speaker twist/6.3mm jack combo sockets for cabinet connection, two XLR outputs, cab-sim switches, the power switch, and an IEC socket for the internal power supply. LEDs for power, temperature status, and over-current protection provide visual feedback on operating conditions. In practice, this all means phenomenal power, straightforward handling, and universal connectivity for everything from the very smallest to almost the very largest setups imaginable.
The Seymour Duncan PowerStage 700 is an excellent solution for guitarists who shape their sound with pedals or modelling systems and thus need a neutral but high-powered amplifier. It's ideal for bands who want to keep their touring rigs as light as possible – while still driving a guitar cabinet that can move some serious air. In the studio, recording artists also stand to profit from the PowerStage's flexible signal routing, with switchable speaker simulation. The device's simple operation makes it accessible to both professional players and ambitious amateurs, while the rugged build, cooling fan, and internal power supply ensure reliable performance in live situations.
The Californian manufacturer Seymour Duncan is one of the largest suppliers of pickup systems for electric and acoustic guitars, as well as basses. The company founded by its namesake also develops pedals and other accessories for guitarists. The current product range is comprehensive and covers a wide variety of construction types. Pickups are available as after-market products, but are also often integrated by many guitar manufacturers, whether in the USA or the Far East (under the name Duncan Designed). In addition to the well-known models, such as JB, Duncan Distortion and Pearly Gates, many signature models have been created for and named after well-known guitarists of all genres, from Mark Knopfler and Joe Bonamassa to Yngwie Malmsteen and Dave Mustaine.
On stage, the Seymour Duncan PowerStage 700 can be connected right behind a pedalboard, modeller, or multi-effects unit, driving even large speaker cabinets confidently without the need for an additional amp. Its format also makes it suitable as a rack-mounted power amp. The two XLR outputs, with individually switchable cab simulation, send signals simultaneously to FOH, a recording setup, or monitor feeds. In the studio, the PowerStage works perfectly as a neutral amplifier for re-amping or pre-production. Thanks to its immense output, it's also an ideal backup for guitarists who normally use full tube amps or digital rigs, as it can easily replace a fully functional amplifier. Finally, the flexible impedance handling and stereo connectivity make it universally adaptable – whether it's hooked up to 1x12, 2x12, or 4x12 cabs.
