owner of the me50. i recommend you look around for a 2nd hand me50, don't buy it first hand as i think only swee lee stocks them and their prices are outrageous.
the me50 has probably everything you need, even pitch shifting. i also considered the ax3000g and tried it out at citymusic but chose the me50 in the end. i think the ax3000g is more economical and bang for buck. it is also harder to use than the me-50.
i chose the me-50 in the end because i really needed its pitch shifting. i recommend you to look around for a second hand me50 and if you cant find one, then get the ax3000g. both are great pedals and i'm sure they will make you happy
