This thread made me bust mine back out.. I have the Outlier (from Metro forum) modded one and with the gain cranked it gets woofy for me in the mids with a humbucker but with the gain downand the level up, it has a very nice natural gain on top of an already over driven amp. Almost like an extra tube gain stage. Flatter response than a TS type pedal which i also love. Great tones with my Brahma MTS module..
