The Evolution Series microphones consists of four handheld and four instrument dynamic models. For rock and pop vocals, there is the E825 cardioid and the E845 supercardioid and for all-around vocal use you could use either the E835 or the supercardioid E855. The E825, E835 and E845 are equipped with on/off switches. All the vocal mics weigh in at twelve ounces and are housed in a rugged steel-blue metal tube. The four cardioid instrument mics are: the E602 for kick drum and the E604 for closed-miked snare or tom-tom drum applications and the E608 for woodwind/brass or the E609 for guitar cabinets. All these mics are sold with a black velour storage pouch and a one-year warranty. Retail prices for all the mics are less than $350.
