Boss CE-300 Super Chorus (HSR Mar 85)

muzines.co.uk

The Boss CE-300 Super Chorus delivers a stunning stereo chorus effect, thanks to its state-of-the-art analogue delay lines and psycho-acoustic tricks. Its simple yet effective controls allow for a wide range of chorus effects, from subtle to bold, with clarity and refinement. The unit excels in recording environments due to its clean and quiet operation. However, it lacks the versatility of flanging, which requires additional equipment to achieve. Despite its higher price compared to cheaper pedals, the CE-300 is a worthwhile investment for serious recording enthusiasts seeking a superior chorus effect.
