Get to know them!

The Seymour Duncan PowerStage 100 Stereo is a gig-ready guitar power amplifier, loaded with a whopping 100 watts of clean power per each stereo channel. Whether you’re running an amp-in-a-box pedal, preamp, or a modern modeling unit, the PowerStage transparently transforms your rig’s sound into a cabinet-ready signal. What’s more, you also get a full 5-band EQ to further tweak your tone to taste, and there’s even a cab sim switch to add just a touch more life and depth to your sound when going direct into a DAW or mixing board. Up onstage or in the studio, the Seymour Duncan PowerStage 100 Stereo is a powerful, portable alternative to a traditional guitar amplifier setup.

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

Clean, 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 100 Stereo 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 4 x 12-inch. This makes the PowerStage 100 Stereo a favorite among traveling guitarists who rely on rented backline, as well as 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 100 Stereo electric guitar amp is housed in a compact and attractive enclosure that will nestle right in with your other pedals. Not only that, but the PowerStage 100 Stereo is a featherweight. When you’re done pummeling your audience's ears at the gig, simply pack up your pedalboard, and your amp is taken care of too.

Plenty of tone-shaping possibilities

The Seymour Duncan PowerStage 100 Stereo electric guitar amplifier is engineered to get the very most from your pedalboard. And thanks to a powerful 5-band EQ, it sounds great as its own clean channel as well. The onboard 5-band EQ works with the power stage to match up to any cabinet. No matter what you’re running on the floor, the PowerStage 100 Stereo will handle it flawlessly.

Seymour Duncan PowerStage 100 Stereo Features:

  • Compact pedalboard-sized power amp designed to amplify your pedal- or modeler-based rig
  • 100W of pure clean tone available on each stereo channel at 4ohms
  • Far more portable than a traditional amplifier setup
  • Bypassable 5-band EQ gives you a seriously versatile level of tone-shaping power
  • Built-in bypassable cabinet simulation to add a bit of life to your sound when going direct to a DAW or mixing board
  • Allows you to use your pedals as the rig’s front end
What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!
