Details Reviews FAQs
  • Updated analog chorus based on vintage 80’s CS-9
  • Wide range of standard chorus effects
  • Unique “spatial” effects unavailable with other chorus units
  • Panasonic MN3207 Bucket Brigade IC
  • Delay Time and Effect Blend controls
  • Stereo outputs
  • True Bypass Switching

With a circuit based around the Panasonic MN3207 Bucket Brigade IC, the CS-9 Pro’s chorus effect is bold and resonant without sounding harsh.  Unlike the somewhat sterile sounds of its 80’s predecessor, the CS-9 Pro has an edgy, almost grainy quality that keeps your tone articulate and prevents wash-out.

The CS-9 Pro’s custom-tuned oscillator circuit provides enough speed for authentic rotary speaker simulation, and just the right amount of modulation for a lush vibrato that won't leave you feeling queasy.

With its Delay Time control the CS-9 Pro can venture into Flanger territory, adding a resonant, hollow quality to the effect that’s great for solos.

A top-mounted Blend control allows you to adjust the level of the Chorus effect to set it back in the mix against your dry signal.

A unique feature of the CS-9 Pro is its ability to create spatial effects that add dimension to your guitar tone without the traditional Chorus wobble.  With Speed and Depth set low and the Delay Time at max, the Pro thickens your sound much in the manner of a double-tracked guitar, adding girth and life without excessive modulation.

The CS-9 Pro features stereo outputs for mono, stereo, or inverted mono signal routing.

The CS-9 Pro is essentially the same as Maxon’s CS550, but in a smaller chassis and with battery or AC power options.

TECH TALK:

The CS-9 Pro circuit is similar to the Arion SCH-1 Stereo Chorus, or an updated Boss Chorus Ensemble.  A high-impedance input buffer passes next into a Compander stage that acts as a compressor/expander, bringing the input level of the signal up to an ideal output level and keeping it there as the signal decays – this provides a good signal-to-noise ratio and gives the chorusing section a nice, steady signal to modulate.

The Chorus effect is produced by a Panasonic MN3102 low-voltage clock driver IC and a Panasonic MN3207 BBD IC which is controlled by the MN3102.  Though the 3207/3201 combo has less delay range than other BBD’s of this type, the difference is negligible and the inherent decay of signal quality adds “vintage lo-fi warmth” to the signal.

After the Chorus section, the signal hits another Compander to level everything out and is then fed to an output buffer.

At the end of the circuit the signal is phase-split and sent to the two low-impedance stereo outputs - Output A is in-phase and Output B is phase inverted (90 degrees out of phase).

The CS-9 Pro features Mechanical True Bypass switching on both outputs via a Fujisoku 4PDT switch.
