A Ton of Power for Your Pedal-based Rig

Seymour Duncan's PowerStage 700 is a miniature power amplifier engineered to attain the best tone and performance from your pedal-based electric guitar rig. Small enough to fit into your gig bag at the end of the night, the PowerStage 700 still pumps out an astounding 700 watts — more than enough to power any combination of guitar cabinets. And the onboard stereo I/O, cab-simulated output, and 3-band EQ make it extremely versatile, no matter what pedals you are using for your front end. The PowerStage 700 is the performing guitarist's new favorite tool.

Note: This device is intended to drive a speaker cabinet and should not be placed in front of an amplifier or pedals.

700 watts per side of clean power

More and more guitarists are getting hip to the great guitar tones that can be achieved by running your favorite guitar pedals — especially the amp-in-a-box variety — directly into a great power amplifier. That's exactly what the PowerStage 700 is designed for. By utilizing this setup, your stompbox tones receive enough juice to scream through anything from a compact 1 x 12-inch cab to a wall of 4 x 12-inch cabs. This makes the PowerStage 700 a favorite among traveling guitarists who rely on rented backlines and many of the gigging players around Sweetwater.

Convenient size

Unlike the heavy and large solid-state power amplifiers of the past, the Seymour Duncan PowerStage 700 is housed in a compact and attractive enclosure that looks great when standing on its own. Not only that, but the PowerStage 700 is a featherweight. When you're done pummeling your audience's ears at the gig, this amp will slip easily into your gig bag without undue stress on your shoulder. And it's easily rackmounted for convenience.

Plenty of tone-shaping power

The Seymour Duncan PowerStage 700 is engineered to get the very most from your pedalboard. And thanks to a bevy of onboard features, it sounds great as its own clean channel as well. The stereo inputs and outputs allow for a discrete stereo or wet/dry rig. The onboard 3-band EQ works with the power stage to match up to any cabinet. And the cab-simulated output makes running directly to the board a convenient and great-sounding option. No matter what you're running on the floor, the PowerStage 700 will handle it flawlessly.

Seymour Duncan PowerStage 700 Features:

  • Compact power amp for a pedal-based guitar rig
  • 700W of power per side easily drives any amp cabinet
  • Small enough to fit in a backpack or gig bag and easily rackmountable for more permanent rigs
  • Discrete stereo inputs and outputs for getting the most from your pedals
  • 3-band EQ in the power section available to dial your cabinet's tone with each venue
  • Selectable cab-simulated outputs are fantastic for going direct

Reviews

Great solid state amp
I first tried the PS200 with a 4ohm cab and for the most part it was loud enough to play with a loud drummer but didn't have the extra headroom for when things got really loud in the jam room. I just got this PS700 and with a 4ohm cab it's plenty loud enough. My pedals sound great through it. I use the KSR Ceres as my preamp and it all sounds amazing. This thing will run two 4ohm cabs in stereo. It doesn't say that in the literature but I called Seymour Duncan to verify. The stereo outs are independent of each other like having two separate amps in this thing. Lightweight and bad***.
the dude
For pedal guys, here's your unicorn. It's PLENTY loud. Kemper, HeadRush, helix, players need one of these to complete the live rig.
2 complaints. When you rack mount the 700 it takes up 1 1/2 spaces which is kinda annoying. It sets my OCD off. Also annoying, the power switch is in the back.
Pro tip: ALWAYS turn the volume to zero before turning off. Kinda like a standby switch. Also, I used colored tape to indicate the inputs matching the outputs.
I am a tube amp snob but I love this power amp.
I have played only tube amps for over 35 years. It's safe to say that I am a fan, and if the love of tube amps is a cult, you can sign me up. Then one day, I bought a Helix rack. My tube amps are valuable and could potentially fail on a four hour gig, so I took a chance on a Helix. I really like it. I bought a rack mount tube power amp which I loved but I blew it at a gig. Luckily, I use in ear monitors and the Helix went straight to the board, my in ears, and front of house speakers. So I made it through that show. But I had another show the following week, so I needed a solution.

So, I bought this power amp to replace it while I sent my blown Fryette to the factory for repair. We had shows to play immediately so I couldn't wait for a repair. I figured that if it's good enough for Dave Mustaine it's good enough for me in my 80s hair bands cover band. Boy was I pleased when I played it for the first time. This thing has balls. I set all dials at noon, so neutral, and let the Helix rack color my tone. I highly recommend this power amp. It's also a lot lighter than the Fryette.

It performs excellently for both guitar and bass.

Fantastic amp!
I got this to pair with my Tonex pedal. Into a stereo 4x12 it has more than enough power. VERY LOUD! The eq works very well, and the amp sounds good as a clean channel by itself. Dead simple operation, hard to provide an argument against this thing. Just for the sake of discussion, I own several tube amps. Mesa Boogie, Orange, Fender, etc. Does this sound like them? No, I didn't expect that it would. It does "feel" like a guitar amp though. It is very useable, even at low volume, a great sounding power amp to use with your preamp pedals in a live situation. I am very happy with this unit.
