Powerful, transparent stereo amplification in a compact design.
The Seymour Duncan PowerStage 100S stereo guitar power amplifier provides pristine, transparent amplification for your preamps, pedals and modeling units. With 100 watts of power per channel, the PowerStage 100S delivers your stereo signal to cabinets or a PA system with clarity. It's ideal for guitarists who want a lightweight power amp solution for their complex pedalboards and rack units.
Transparent Tone for Modern Setups
The PowerStage 100S is designed to accurately amplify the tone crafted in your preamp or multi-effects unit. Its class-D power amp design adds no coloration to your core sound. Whether you want punchy overdrive, shimmering chorus or spatial reverb, the PowerStage 100S sends the full frequency range of your effects to your cabinets. For direct recording or live sound, the balanced XLR outputs feature analog cabinet simulation to emulate the resonance of a guitar cabinet.
Sculpt Your Sound with EQ
While the PowerStage 100S aims to transparently amplify your input signal, its 5-band EQ provides tone shaping when you need it. The EQ ranges from 80 Hz to 10 kHz, allowing you to cut boominess, boost presence or roll off harsh highs. Make broad changes to suit a room or fine adjustments to match the tone in your head. The EQ also comes in handy for matching the sound of bi-amped or stereo rigs.
Compact Yet Powerful
Despite its diminutive size, the PowerStage 100S pumps out 100watts to each of its stereo channels, providing more than enough power for most gigging guitarists. It's lightweight and sized to fit on a large pedalboard, ideal for fly dates and clubs with limited stage space. Don't let its small stature fool you—the PowerStage 100S packs professional-level power and performance.
Simple Yet Versatile
While packed with useful features for modern guitarists, the PowerStage 100S remains straightforward to operate. A single volume control and 5-band EQ provide tone adjustment. 1/4" inputs accept signals from your preamp, modeler or effects loop. Balanced XLR outs connect to PA systems, recording interfaces or bi-amped rigs. Despite its simplicity, the PowerStage 100S capably powers a range of setups from ampless preamp rigs to stereo wet-dry-wet configurations.

- 100W per channel stereo power amp
