Seymour Duncan PowerStage 170

The Seymour Duncan PowerStage 170 is a compact, lightweight power amplifier engineered for pedalboard integration and portable rig deployment. Its diminutive footprint—just 5 x 5.24 x 2.84 inches and weighing only 2 lbs—makes it practical for gigging musicians who need serious power without the bulk of traditional amp heads. The unit delivers clean, efficient amplification via Class D circuitry, ideal for direct-to-PA workflows or as a standalone power stage for amp modeling and profiling devices.

Power & Amplification

This amp generates 170 watts at 4 ohms, sufficient headroom for medium to larger venues and studio work. The Class D topology ensures minimal heat generation and power consumption while maintaining output integrity, making extended sessions practical without thermal concerns. Output impedance runs 4–8 ohms, accommodating standard speaker loads with flexibility.

Controls & EQ

The three-band EQ provides surgical tone-shaping capability: Bass at ±13 dB (87 Hz), Mid at ±13 dB (712 Hz), and Treble at ±13 dB (6.61 kHz). A Level control spanning 0 dB to 47 dB allows precise output calibration for any signal source or venue requirement. These tools let you dial in your preferred voicing without relying on external EQ pedals.
