This pre loved CS-3 Compressor Sustainer Pedal was made in Japan and is in good used condition
The BOSS CS-3 is a guitar effects pedal that functions as a compressor and sustainer.
Originally introduced in the mid-1980s, it is designed to even out dynamics, add sustain, and subtly shape tone.
Made in Japan (MIJ) units are considered the classic version, praised for build quality, reliability, and a slightly warmer, more natural compression than later Taiwan-made or overseas models.
Controls:
Level — sets the output volume after compression.
Tone — adjusts brightness of the compressed signal.
Attack — controls how quickly compression is applied.
Sustain — determines the amount of compression and how long notes are held.
Compression & Sustain:
Smooths out volume differences in your playing, making soft notes louder and loud notes softer.
Enhances sustain, allowing notes or chords to ring longer without loss of clarity.
True Bypass (on later models) vs Buffered Bypass:
Classic MIJ CS-3 uses a buffered bypass which preserves high-end tone over long cable runs.
Power:
Runs on a standard 9V battery or a 9V DC power adapter.
Input Impedance:
High impedance input (~1 MΩ) ideal for guitar and bass, works well with passive pickups.
Lead guitar: Adds sustain for solos, smooths attack, and helps notes ring evenly.
Rhythm guitar: Evens out dynamics for consistent chord volume.
Recording and live performance: Provides subtle compression to stabilize tone without overprocessing.
Works well for clean, overdrive, or mild distortion setups — maintains clarity and articulation.
Classic circuitry: MIJ units use early components and circuitry known for a slightly warmer, organic tone.
Build quality: Sturdier than later Taiwan or overseas models, with solid construction and long-lasting footswitches and jacks.
Vintage value: Often sought by collectors and players for both tone and durability.
Slight tonal differences compared to modern CS-3 units — MIJ tends to have a smoother compression curve.
The MIJ CS-3 is a classic choice for guitarists looking for smooth, reliable compression with sustain, excellent for both live performance and recording, especially for players who value a slightly warmer, vintage tone.
