Seymour Duncan PowerStage 170

The PowerStage 170 is a compact power amplifier built to integrate seamlessly into pedalboards and mobile rigs without sacrificing output capability. Its diminutive footprint and Class D efficiency make it a practical solution for musicians running amp modeling devices or direct-to-PA setups who need serious wattage in a portable package.

Power & Amplification

This unit delivers 170 watts at 4 ohms, providing adequate headroom for medium to larger venues and studio applications. The Class D topology minimizes heat generation and power draw while maintaining clean signal integrity, making extended playing sessions practical without thermal stress.

Tone Control & Output Calibration

A three-band EQ offers precise tone-shaping with Bass, Mid, and Treble controls each providing ±13 dB adjustment at their respective frequencies. The Level control ranges from 0 dB to 47 dB, allowing you to match any input signal source and adapt to venue-specific requirements without relying on external EQ hardware.
