Well, in the Korg AX1G that i got recently, the person who sold it to me had this setting called, "Liquid" basically heavy wah, and heavy distortion. I loved it, especially when i tremolo picked using it.
my favourite on the krog ax100g is my modified version of this preset called static - i switched the expression from volume to wah - modified the phaser of the modulation effect and also one of the drive channels - the channels are now distortion/clean with the settings as described.... soudns awesome
