As a potential buyer of Helix i actually have held off buying a Helix since 2015 purely because i know the Reverbs are lacklustre at best, i would have hoped for almost 2 years a few firmware updates addressing this issue If the Helix is to continue to really stand out in a crowd all it has to do is go head to head with Strymon FX since its amp modelling is obviously amazing but, i want more... Still i think there is definite room for improvement... Personally i rely heavily of reverbs and whislt the delays are quite decent i think there is still some overdue firmware updates.
Granted if you are just a blues or rock player it probably has you covered, but for those ambient FX lovers we also need something thats going to make me not buy 3 strymon pedals instead. I think the helix is almost there but not quite especially if TC electronics has better sounding verbs... please update your verbs Line 6.
