Re: Cover Bands and whatever "authentic sounds" (or the possible need for them)
Fwiw, I'm making my living playing mostly "corporate gigs" since around 30 years by now. This includes all kinds of things, more or less Top 40 stuff, sideman work for somewhat halfway wellknown singers, musical stuff, even some tribute acts.
And not even once (!) in all these years have I been asked to replicate any specific sounds nor has anybody ever complained about the sounds I was coming up with. The most I've been asked for soundwise was some playing request such as "drive /w tremolo" on a musical sheet. Otherwise, people have always been happy with what I'd come up with on my own - and I never cared for authenticity at all. Others do so even less (apart from some corksniffer guitarists). Heck, most MDs I worked with wouldn't even get the difference between a single coil and a humbucker as long as the sound was clean, halfdriven or fully driven enough to suit the music.
What I'm saying is: Authentic sounds might be important for us, the players. For pretty much anyone else, they aren't.
Having said that, in the 3 years of gigging with a Helix, I have only used one single patch per gig (different patches for different gigs, but I never even once used more than one per show).
And fwiw, FOH folks love it, believe me! They're often getting quite mad if you're coming up with totally different patches for each tune. Live playing isn't a studio recording - and unless you're a big act, trying to replicate studio tones isn't making much sense, either.
