best that you try out both to suit your playing style..

but reviews favor the vox more than the cube...

check out ckmusic they hv sale now on vox ad30vt and the vt-xl too..

last i heard from themm,all the advt and advt-xl series only left 1 more ad30vt and 1 more ad50vt-xl...hehehe..

all the best....!
