Yep, just downloaded a freeware spectrum analyzer...fits the bill.
I guess it's more curiousity than anything. I suspect the bass control on my TRB 6ii is quite wide and sometimes I turn it hoping to get more of a 'thump' and the more I turn it the boomier it gets. I have a Klark-Teknik parametric EQ but usually don't lug it or any rack items around for that matter.
So yea, curiosity.
