well i've recently been to kollkatta, to a place called braganza musicals. i have the g2 with me, went in to check out expression pedals, but some pedals calle dexpression station was costing above 10k, so i asked the owner of the shop who always give you indepth information on any muscal or electronic item u ask for, i asked him the same question, he said if you buy a normal expression pedal costing 2000, u will be only able to change patch volumes thats all and nothing else, and where as with g2.1u u can use the harmonised pitch shifter, change parameters, change volume and stuff like that! and that too the g2.1u also has an additional control in input so u can use an additional pedal! and looks wise too its great! but right now im fine with my g2 its works amazing. easy interface,
