Fooling with the 4OTF tonight a little and noticed if you lower the drive, but up the drive vol (no breakup, just clean), you can use the H/LPFs to fully tweak the tone. In other words, you have just a HPF or LPF or both if you want. (Only the drive side is run through the filters. The clean vol is your unaffected signal you can blend in as desired and does not go through the filters.) I can't believe how much I like this pedal.
