Drive Series effects are designed to be connected in front of a "clean" channel inputs of guitar combos or amplifiers, and do not have a cabinet simulated output as the Legend Amp Series. These pedals allow guitarists to obtain warm, crisp, natural tube sounds of their favorite high gain amplifiers, while preserving individuality and tone of the instrument and equipment. In the Drive Series, AMT uses new original circuitry solutions developed by AMT specialists based on real actual tube stage emulation and response. The result is bright, rich, full, and powerful distortion sounds. The AMT M-DRIVE was designed for guitarists looking for distoriton sounds similar to that of Marshall JCM800* amplifier.
