I've never really liked the sound of the CH-1. It feels a bit "grumbly" to me. I don't think Grumbly is in the dictionary so it might not tell you a lot . I much prefer the CE-2, CE-5 or DC-3 for a different kind of chorus.
They're very different and I feel like inventing a couple of more words to describe them but I'll try not to I can see why their names are similar. It sounds to me like they tried to emulate the DC-2 with the digital circuit in the DC-3. It wasn't quite possible with the digital circuitry and they ended up with a pedal that to me sounds better than the original DC-2. I escpecially like how the DC-3 sounds with long single notes. The DC-2 sounds good too but it's a bit limited with the 4 push buttons and I think they're a bit over the top and I can't reduce the chorus depth.
ok, thanks. i really wanted a DC2 because im a little bit lazy in adjusting knobs to find a good setting. so the buttons factor was an advantage for me. although i would like to try both. anyway, thanks again for the info.
