[quote name='Prime_BASS' timestamp='1339714755' post='1693378'] Just took delivery of mine. It is a low pass filter but it cuts the super low end that you probabaly don't hear, and it's more to help amps run without clipping and cabs run better as it isn't wasting energy on frequencies that don't matter. some amps already have this sort of protection anyway, but some only when things are getting really loud. Havent had a good play yet but I can hear a difference and it is harder to clip the input aswell.# Not sure how to set up my compressor to rid the boom and bring highs in line though. something to do with comp and threshold though I think?

Isn't the Thumpinator a high pass filter set to @ 30hz? Regardless, it certainly seems like a handy bit of kit.
Mr Fudge, what cabs are you using?

In small venues you'll have a lot of soft furnishings that soak up sound. In the "bigger more hard surfaced venues" those sounds won't be soaked up & reflected back to you, making them twice as prominent. EQ is your friend. In the bigger venues, turn the VLE up a couple of dots & roll the bass back a couple too.
I used to not use the filters at gigs but now I use a mix of both VLE & VPF. It's like finding that 6th gear on your new car.
