Based on the now-defunct Maxon CS505 Stereo Chorus, the PAC-9 takes that venerable design and brings it into the 21st century.

Featuring an improved oscillator section, the PAC-9 can perform rotary-speaker simulations and tremolo-chorus effects that were not previously attainable with the CS505. Pure and Bright switches provide a variety of useful chorus effects while performance is kept dead-quiet thanks for Maxon's proprietary RMS noise reduction circuity.

Topped off with inverse stereo outputs and mechancial true bypass switching, the PAC-9 is the future of analog chorus effects!
