Almost two years into the process of building his perfect distortion box, he almost had it, but not quite.  Only one thing was getting in the way of creating his masterpiece:   work.  Only one thing to do:  quit.  Now he had the time to devote to his obsession.  Of course he needed to pay bills, so freelancing on top of designing was the only way go. “I must have put in around 90 hours a week for a year straight!” he told me.  On top of all of this was the decision to relocate to Finland three years ago, where a vibrant rock scene and favorable start-up environment could stoke his creative fire musically and electronically.  And so, the inexorable journey of building and sharing his tonal voice commenced.  And together, with friend Hugo Villarroel Navarro in Chile, (sales and artist relations,) and most recently, Spencer Doren of 3Leaf Audio in Seattle, (production,) this builder and his company have solidified this brand as a serious contender in the world marketplace;  in less than three years.

The builder is Douglas Castro.  The company is Darkglass Electronics.  And the pedal is the Microtubes B3K.  From the beginning, friends, players, and sound engineers have praised its tone and its simplicity so Doug knew he was onto something.  Since then, it’s found its way into the hands of Tony Levin, Jeff Rouse (Duff McKagan’s Loaded,) Justin Meldal-Johnsen , Alex Webster (Cannibal Corpse,) and many others.

It was announced in June of 2012 that all Darkglass pedals, including the B3K, big brother B7K, and all future designs, would be manufactured in the U.S.  With Spencer now in charge of production and quality control, availability of Darkglass pedals is greater, the price is lower, and the quality of the pedals; with the upgraded relay bypass switching, beefier toggles, and tightened up circuit design, is better.  Take your pick!
