Amp Switch (Fullerton | London | Dartford) - The Amp switch selects
between one of three classic amp models built into the ACS1.
Designed from the ground up using a detailed physical modeling-based
simulation of the original circuity, each of the cascading triode/filtering
stages have been faithfully replicated creating complex tones, rich with
even harmonics and subtle intercomponent asymmetries/inconsistencies.
The power amp staging has been highly biased to retain plenty of dynamic
warmth and headroom during Class A behavior at low gains, shifting into
an increased sensitivity and overdrive in Class AB saturation through to
complete Valve breakup at maximum.
Fullerton: Inspired by the classically snappy and clear Fender® Deluxe
Reverb. Clean headroom that blooms into the fat, rich breakup that
players have come to love over the years.
London: Inspired by a 1962 Marshall® Bluesbreaker with a harmonically
rich, valve-driven breakup. Perfect for sustained lead notes with tons of
gain on tap and a punchy mid-ranged voicing.
Dartford: Inspired by the legendary and jangly tones from a 1960s Vox®
AC30 with all the bite and chime from the British Invasion. Higher gain
settings offer up plenty of saturation that represent the loudness and
punch of the original amp cranked.
