Seymour Duncan Studio Bass Compressor Pedal

The Seymour Duncan Studio Bass Compressor is a compact, pedalboard-friendly unit engineered to deliver transparent dynamic control without coloring your bass tone. Its modest footprint and lightweight construction make it easy to integrate into any rig, while the true-bypass design ensures your signal remains unaffected when disengaged.

Compression Control & Tone Shaping

This pedal uses a Voltage Controlled Amplifier (VCA) topology with soft-knee compression that ranges from 1:1 to >20:1 ratio, giving you everything from subtle dynamic leveling to aggressive limiting. The adjustable attack speed spans 8ms to 27ms, allowing you to control how quickly the compressor responds to input transients, while the +33dB maximum gain provides sufficient makeup gain for any bass signal level.

Audio Performance & Connectivity

The pedal maintains extremely low noise at -110dBV (400 Hz–20 kHz, input shorted) and distortion below 0.3% at 300mV RMS output, ensuring studio-quality signal integrity. Input impedance of 1 Megohm and output impedance of 2.75K ohms maximum guarantee clean interfacing with bass pickups and downstream gear, while the 3 Vrms maximum input level accommodates both active and passive instruments.
