From what I hear, the Broughton RFE is the bees knees of filter pedals, but with no drop in sight I guess the LP/HP filter will do for now.
I didn't care for the RFE, it changed my tone too much. I lost my nice tight bottom that I liked to dial in with the regular HP/LP pedal so I went back to it. I would say the bees knees in filter pedals is the Messenger Jr....LP/HP pedal with sweepable mids, EQ, and DI!
