Boss GEB-7 or GE-7B? Which is better for a post-dirt section harshness reducer.

[AinsleyWalker]

So I was looking into the differences between the GEB-7 and the GE-7B, and obviously the frequencies available are the main difference.

I plan to get an EQ pedal to use after my Rat/Big Muff (as I've said in other topics) to reduce some of the high end/boost low end and I was wondering which of these two pedals would be best suited?

I've looked into the Boss PQ-3B as well but they seem quite hard to get hold of and I've heard they are less versatile than a graphic EQ
Thanks!
