Source Audio's new One Series digital pedals are simpler, more streamlined by the standards if the company's Soundblox pedals, but they are no less potent. The Vertigo tremolo features emulations of vintage optical, harmonic, and bias trems, but parameters can also be customized via the iOS interface. Prices should be right around $149 when they hit the street this spring.
