Just received my Catalina Chorus pedal today. I put in a a chain with my two digital chorus effects I have. One is an emulation of Classic Chorus, the other BI chorus which has that fuller sound.
My digital chorus effects sound very good. Never had a complaint about them. When I compared them to the Catalina, the SD chorus had a fuller sound, a little more up front sound. Going back to the digital chorus it sounded thinner and a little laid back. They have great presets in the manual for different chorus sounds.
Not to my surprise, this is a wondeful chorus pedal that has a lush full sound. The tone knob is an extra bonus as it can help reduce too much brightness or add more in. Dynamic control is another bonus that makes me smile. I then went stereo between my Fender Twin RI and Mesa Boogie amp. It clearerly sounded better than even the Roland Chorus amp. By reducing the depth and delay you can control the sound so it's more gentle and not as thick. This is not a one trick effect pedal. Can't imagine being happier with another chorus pedal. The Boss Waza Chorus looks great too but the features including a mix knob make this my favorite chorus pedal. With my setup it did not reduce the low end either.
