Seymour Duncan PowerStage 170

Seymour Duncan PowerStage 170

The Seymour Duncan PowerStage 170 is a compact, lightweight power amplifier designed to integrate seamlessly into home-studio signal chains and direct-to-interface recording workflows. Its diminutive footprint—just 5 x 5.24 x 2.84 inches and weighing only 2 lbs—makes it practical for studio setups where rack real estate and electrical load are constraints. The unit delivers clean, efficient amplification via Class D circuitry, ideal for monitoring amp-modeled tones, profiler outputs, or as a dedicated power stage for guitar processors and synth modules.

Power & Amplification

This amp generates 170 watts at 4 ohms, delivering sufficient headroom for studio reference monitoring, tracking through speaker-simulation chains, and auditioning multiple speaker configurations. The Class D topology ensures minimal heat generation and power consumption during long tracking and mixing sessions, eliminating thermal concerns in smaller room environments. Output impedance runs 4–8 ohms, accommodating standard studio monitor cabinets and speaker loads with flexibility.

Controls & EQ

The three-band EQ provides precision tone-sculpting for capturing and refining recorded tones: 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 exact gain staging and level matching across different signal sources and recording setups. These tools let you dial in your preferred voicing without requiring external EQ processors in the session.
