Do you know this firsthand, bongo? I'm quite aware of the difference in knobs and that one pedal is brown and one is blue

The CEB-3 has a knob that's a highpass filter but a lot of dudes prefer the CE-2B. More or less features does not a better pedal make!
I don't care about components inasmuch as saying better quality components equals better sound. I care more about practically, in the real studio/gigging world, which is easier to dial in, which enhances your tone and helps you sit in the mix better, etc etc. I'm pretty sure the LMB-3 would do the job, but if the 2 is better then why wouldn't I get that? Us gearheads do want something more than just "does the job", you know!
I am looking for something that's always on and isn't necessarily noticeable until you shut it off, if I can use the old cliche.
