The preamp sections of the Valvetronix combos rely on Korg's proprietary REMS™ technology. REMS (Resonant structure and Electronic circuit Modeling System) accurately reproduces the complex circuitry in each of the modeled amplifier's signal paths and re-creates the tonality originally created in those amps. It even replicates their unique tone-stack networks so the Valvetronix' tone controls interact exactly as they do in the amplifiers being modeled! Play a new AD60VT or AD120VT and you'll hear and feel the difference immediately.
