I’ve had this issue too playing a couple gigs with it. First gig i had the volume on the amp at about 3/4 to full volume and just not cutting it with my band...2nd set i cranked it all the way and about 1 oclock on the helix....couldnt seem to go much more with the helix before clipping....so i got loud enough but i really dont like not having head room to spare. 2nd gig i started using irs in place of the helix cab models and had much better luck but im finding i just dont like the sound of the powercab....this weekend i set my stagesource l2t next to the powercab and wow did i love the sound of the stagesource way better....and loud....no problem getting volume. So I have to say im not impressed with the powercab so far..either going to return it or it will become my practice amp unless i can figure out what is going on. Bear in mind im only a month into using the helix and still learning
