"Hamilton runs all of his pedals in front of the amp and controls the rig with a Custom Audio Electronics RS-5 MIDI Foot Controller designed by Bob Bradshaw. The signal starts with a Hello Kitty-modified Fryette Valvulator before going into an MXR Custom Audio Electronics Boost/Overdrive. From there the signal hits a Real McCoy Custom wah, Eventide TimeFactor, MXR Bass Octave…" states [this article](http://www.premierguitar.com/articles/21355-rig-rundown-helmets-page-hamilton).more
Along with the M80 Bass DI, this pedal has been on my board for more than seven years. It gives the full body octave down with excelente tracking from bottom to top. Put the M87 Bass Compressor before this pair and there are the 3 pedals that are switched on in my board most of the time! I really recommend.
