True... they're still Muffs at heart, after all. Although IME, the consistency between SMD-based EHX pedals is excellent - perhaps to a fault (i.e., the Nano Clone

).
It's sorta like comparing boutique Muff clones - unless you've significantly modified the circuit and/or added new controls, it's still very much like a regular Muff, perhaps with more mids or clarity. But with each control or mod you add, you step away from the Big Muff and step into the sonic territories of other fuzz pedals.
