All I can say is WOW! A initial setting between the suggested "Deep Tube Bass" and "Svt Bass" is incredible. Warms and rounds the tone, and adds a good bit of "Grit" and "Punch". My head and cabs are somewhat bright and almost too clean, even with tube pre in the head. I've worked a few "tube emulation" pedals through this rig to try to warm it up and add some depth to no avail. This pedal is the ticket.
