Okay, heres my opinion:
Boston EQ
The bandwidth of this pedal is much better to my ears compared to the Behringer. It also has a greater amount of volume boost compared to the Behringer. The way each band slider is tailored is very well centered, and the boost (specially in the mids) is very good.
The pedal is also a bit more transparent when bypassed compared to the Behringer and seems to have a lower noise floor compared to the other.
Behringer EQ
The Behringer has a cleaner sounding frequency spectrum overall, with the boost being a little on the weak side. The noise floor is bearable, being a lot better than the Boss GE7. One thing I like about this pedal is how its more responsive to the dynamics of your guitar, but the EQ tailoring would be a little weaker compared to the Boston.
Also, value would favor the boston, which is cheaper and has a metal casing compared to the Behringer.
Either way bost pedals are good, but in different aspects.
I guess it boils down to:
Dynamics vs. Transparency
Add ko lang sa napansin ko between Boston and Behringer
Yung Behringer kahit lahat naka- 0 (zero) ang sliders, iba na agad ang tunog mo, pero sa Boston pag naka- zero lahat ng slider parang naka- off lang sya..
