You really can't hear the difference??
It was really noticable to me. The CE-5 takes a lot of bottom end out of your tone. Deftones guitarist Stephen Carpenter uses one, but his tone is already really fat and punchy because of the guitars and marshall amps that he uses.
Think of the intro to "Be quiet and drive"
The CH-1 has more of a classic sound. It is more subtle than the CE-5, but sounds warmer, punchier and doesn't kill your bottom end. It won't take the bass out of your sound. I like it much better, and it is versatile too. You'll get more 'Cure' and 'Smiths' sounds out of the CH-1
Try them both again. You should be able to hear the difference.
