Zoom g1on Vs Digitech element?

which is better.?

Haven't tried those two, but did compare a Zoom unit and Digitech unit in a best multi-fx shootout we did. The Zoom came out on top on that one. If the effect quality is comparable, on price alone the Zoom G1on would be my choice.

Thanks a lot ¿What do you think about vox stomplab?

I gotta tell ya, you may wanna up your game a smidge and look at something like the Line6 M9 or a used TC rack unit like a G Major.... even the lowly G sharp which trades for peanuts is a killer unit though limited in how many effects you can stack... prices aren't bad for the older TC stuff and the effects are spectacular in their idiom. Of course you will need a MIDI controller to change patches which may be over budget... I have also seen people use the floor varieties of the PODs for effects only with pretty good results, especially the POD HD series. Again, its now older tech so the prices are low in the used market having been superceded by Helix...

my experiences with the Vox digital effect have been underwhelming, though the standalone delay, the time machine I think? its okay, as are the similar delays in the stomplab

I have never been too impressed with Digitech and I am thrilled they revived the old DOD brand.

so amongst your 2 initial options? go zoom, they've gotten a lot better the last 15 20 years.... though I still say look at some discontinued TC units or maybe an M9 or used floor Pod....
