I have to chime in on this one, the chorus on the Zoom MS60B is fair from desirable IMO/IME. That was the main reason I had bought it, for chorus. It is, in the end, a multi effects pedal so I cant really fault it for trying. Its a decent chorus. If I were to go with a chorus pedal, and hopefully someday I will get one, I would go with the Tech 21 Boost Chorus. Ive heard it in action and I personally think it blows most other choruses out the water. I have worked with Boss choruses before and they are ok. I like shimmering and pronounced choruses. The Boss just didnt do it for me. BUT, their flanger, the BF3 on the other hand, did to it for me. Its a great pedal and you can even get a trem sort of effect out of the gate on it. I am actually using the BF3 more as a chorus on my board at the moment and I have a TC Vortex for a flanger. These pedals suite my needs for now. Although, as I had said before, I really want a Boost Chorus. I think if chorus is used correctly and at the right times, it can be really awesome. Adds a lot of depth to certain passages. I tend to use flange, chrous, trem and delay a lot together. It is a lot of fun.
