I just replaced my EBS UniChorus with the MXR Black Label Chorus ... is a much more subtle chorus but is EXACTLY what I've been searching for.
Describing sound is always tricky, but compared to my EBS Unichorus, the MXR Black Label Chorus is a deeper, darker and earthier (?!?!) to my ears ...
On it's own, it really fattens the sound nicely. Does NOT add mud at all, just fattens it while retaining clarity. Full spectrum of tone ... no apparent loss of lows. As far as I'm concerned, it's perfect for bass. But again, it's subtle. Whacked out drippy gooey tones will not be found with this pedal.
Conversely, it's the type of pedal that I may be tempted to leave on more often than not, and combining it with other pedals is where it really shines. From what I understand, Zakk Wylde helped design it to work in tandem with his distortion - to warm it up a bit. Combined with my EHX Bass Muff , and also the Micro POG, the addition of this chorus is just awesome ... not cool, not trippy, not extreme ... just very musical and the last chorus I'm buying!
I play passive Fenders (both J's and P's). My fave setting is:
Level (blend): Full
Rate: 1 O'Clock
Depth: 2 O'Clock
Low (goes from "cut" to "flat): 1 O'Clock
High(goes from "cut" to "flat): 3 O'Clock
