Great unit, the one here has over 450 shows on it.
IF you tweak long and carefully, you can get everything from an upright clone sound to Mars Cowling(Pat Travers) Jet Flanger bass sound to a Ric clone....and all points in between. 16 "channels" of the 64 are mainly used here.
PS: The octave sim can be rigged to let a 4 string come very close to a 5 string down to low A if you play carefully. It is entertaining to use a low A during live performances. Let's one avoid carrying a 5 string for only 3 songs.....
If you want to find truth, start by turning off your television.
