I understand. But it is a pedal that I have Zerofive regrets about. It makes such a huge improvement to the bottom without the stupid low freqs we don't need to hear. I also use an HPF at the final but the Lowrider seems to add the low goodness without causing anymore low end nonsense. Hard to explain without using it. As old as I am I don't remember the Pultec trick from the studio dayz, I was there, I recorded many things many times and maybe they used it but I wasn't paying attention. But forward to today, live, I love it!
