So I play with an artist who recently signed with a really important booking agent. We've got a bunch of opening gigs this summer for major artists - I'll be playing a few stadium shows, etc. We've got a stretch of 7 shows in 7 days - often with a 6-8 hour drive between each city. We fly out to the first, where we also grab a rental van, and go from there. 6 out of 7 shows are supplying backline, but we've got one show in the middle that won't supply a backline amp for me. We don't really have room in the van, so to play this show - which is already sold out in front of over 10,000 people, I need a direct setup. Now here's the rub - I don't typically like digital modelling. I'm generally a tube amp purist (I even build/modify/repair amps as side income), and the whole workflow of programming generally isn't my style. But I'm going to have to suck that up for this gig. I don't really feel like investing in a unit yet, but I can easily rent either a boss GT-1000, GT-1, or Helix, Helix LT, or HX Stomp. That said, I went to a shop a tried out a Helix LT through a power cab, and while it might have been user error, but I couldn't get a sound that sounded anywhere near as good as a basic tube amp. The sounds I need are pretty simple - a lot of old school soul, james bond-ish guitar sounds. A clean-ish fender sound is typically home for me. Any advice on getting setup quickly with one of these units, and getting a good sound? I've got about 2 weeks to get ready, but can't spend a crazy amount of time on this, as I will be spending a lot of time in rehearsal already as it is.
