This model is an amp simulator based on the sound characteristics of the legendary Soldano® SLO100* amp head (OVERDRIVE channel), which set a benchmark for hi gain amps. The reason you find the sound so familiar is because you’ve been hearing it on gold records since 1987.
PREAMP: Controls the gain amount (pre gain)
BASS/MIDDLE/TREBLE: 3-band EQ that controls the effect tone
PRESENCE: Controls the effect headroom
MASTER: Controls the effect output (post gain)
