The all-analogue SansAmp is, of course, its centre point. Sweepable, semi-parametric, active EQ controls provide professional grade tweakability for any situation. There's a Notch Filter, sweepable from 70Hz to 350Hz, designed to diminish the sensitivity for feedback caused by the resonating, low frequencies of acoustic guitars. A Low Pass Filter, sweepable from 16kHz to 1.5kHz, rolls off undesirable frequencies and artefacts.


Dedicated Reverb function emulates the rich ambience of open spaces, ranging from room to hall.


DLA emulates a warm sounding analogue delay. It features Time and Repeats controls and dedicated Tap Tempo footswitch. CHR is a preset chorus based on pitch-shifting technology for a more natural, 12-string-style sound.
