Chris got introduced to EBS pedals by his friend and bass player colleague Sean Hurley, who’s been using EBS pedals on tour with John Mayer and on many sessions around Los Angeles for several years. Chris Chaney uses the EBS ValveDrive DI, the EBS FuzzMo, OctaBass, DynaVerb, BassIQ and DPhaser pedals. http://ebssweden.com/server/chris-chaney-new-ebs-pedal-artist/more
It's easy to use, with a great response. The sturdy metal housing ensures that you can do just about anything to without breaking (I've dropped mine on concrete with not even a scratch to show for it), which makes it ideal for touring. I usually use mine to make my 4-string sound like a 5-string, and it works perfectly. I still haven't found anyone who can tell the difference. As a regular Octave effect it certainly meets all expactations.
I like this pedal, it has a nice sound and with the different modes you are able to easier fit the pedal to your use, either you want a fat low end or a powerful mid you will get what you are looking for. The only downside of the octabass is that it's not polyfonic(in case somebody wonders what that is it's the ability to pllay several notes at a time) which makes it impossible to play chords with this beauty. It's really a shame cause I love the tone it gives and the versatility to get another octave playing parallell to what you do.
