Legend Amps 2 series preamp effects have 2 channels and are designed to produce clean and overdriven guitar sound. LA2 incorporates original circuit designs developed by the specialists of AMT, which allow to obtain bright and rich sound in the style of the original tube overdrives using low-voltage (9V) power and low current consumption. The early 90's saw the creation of the S amp which became the standard for metal sound. The sound basis for this amplifier was the 5-stage preamp, whose solid and bright sound is reproduced by the S2.
