I've never been a real big fan of multi effects. At least not in the past. It seems that, as time goes by, they're just getting better and better. And, when I talk about multi effects, I'm not talking about the pedals that have a couple of actual pedals in one housing like the ElectroHarmonix Turnip Greens or TrueTone Route 66. Those are a different breed of multi effect and don't really count. I'm talking about the boxes made by Zoom and Digitech and even Boss and Fender that have LOTS of effects in them.
My opinion is probably a little jaded because the old ones are small, in plastic cases that, face it, weren't really made to withstand much abuse, and generally sounded (to my ear) pretty crappy. Back in the day, I'd look at the Zoom offerings from time to time at the local guitar shops. I really wanted to like them. But in my not so humble opinion, they seemed like they would break too easily and weren't very intuitive.
Don't get me wrong, I've always like tech. I work in and around tech, and have done so for nearly 20 years. I just think there's a lot to be said about making tech easily understandable and easy to use for everyone...even the lay person. When I install something on my computer (especially these days), I want it to be plug and play and not have to install a bunch of obscure drivers for it to work correctly, and I want to be able to look at its interface and get a good idea of what I need to do to get it to do what I want it to do. At least on some of those earlier multi effects that I always looked at, this totally didn't describe them. You had to dig for most of the settings, and it was an all or nothing thing. On your preset you either got everything you originally programmed to it or you had to re-program it. If you had some OD and reverb on it, and you wanted to drop the reverb for a bit, well, you couldn't. The preset had OD and reverb so you either got both or neither.
I eventually broke down and bought a Digitech RP50. I really, really tried to like it. Kept it for a couple of years playing with it and trying to get it to a point that I thought it was usable. To do that, I created a bunch of presets and then grouped them. The first would be a completely clean sound against an amp sound. Then I'd add some drive to it on the next slot. Then the next slot would add chorus to that. Then the next would add reverb. Then the next would be the reverb added but without the chorus. And so on.
The sounds coming from it weren't really good. They weren't really bad. They were just sort of ok. I eventually tossed it in the closet where it sat for several years. I found it, pulled it out, and a buddy offered me $20 for it. I just gave it to him. Not like I was using it.
Then along came the GNX3 and GNX4 and some of the other units that did what I had wanted them to do before. You could setup a preset, but turn parts of it on or off. I knew a guy that had one of those (a GNX3 I think). He never actually let me play around with ("you're gonna ruin my presets, dude!"), but it seemed like they tech was finally getting to where I wanted to try it again.
Fast forward a few years after that even, and I eventually picked up a Fender Mustang Floor. I had a couple of buddies that were using the Fender Mustangs, and their amp models seemed really good. That tech had finally come far enough that, even though it still wasn't tube amp good, it's believable enough that most folks aren't going to know the difference. Especially when run though a PA in an environment where there are LOTS of other instruments playing at the same time.
I also like that it's pretty intuitive. You can change the settings pretty easily through the on-board interface or you can use the Fender Fuse software. The on-board interface is easy to understand and use. You do have to go several levels deep on some of the settings to change them, but the basic settings are right there. I prefer the Fuse option though because the settings are all right there.
I actually picked it up for when I'm doing the worship band gig. Nobody but the other guitarist cares if I'm using a tube amp or what my pedals are. The Mustang Floor not only does a good enough job with the amp models and effects that it doesn't sound bad, and it has enough outputs that I can give the sound person whatever kind of line out they want. In a situation like that, it's always been my experience that you either don't get an amp or you don't get an amp on stage with you, so you can't hear it anyways. So the Mustang Floor gives me a sound that I can live with, and makes the sound tech happy too.
The Mustang Floor was discontinued like 3 years ago, and Fender hasn't done anything to replace it. Because of that, I'm waiting on the day that the Fuse software doesn't work anymore. At the moment, it doesn't seem like it's supported at all, so, when it breaks, I guess it'll be done.
However, as multi effects and modeling tech get older, they're still getting better. Nowadays you have the Kemper amps and rack units like the Eleven Rack. I don't know if you can truly consider those multi effects or if they're more profilers, but their amp models and effects are good enough they have been known to fool even some of the diehard cork sniffers.
Looking back on multi effects, if they continue to move at the same pace they have the last 15 years, there'll be no reason to ever lug an amp and board anymore within just a few years.
And, yes, I stole the pics below from Sweetwater because I am too lazy to try to take pics of mine, and couldn't find any stock pics from Fender.

He believes chocolate milk made from milk that is anything less than whole milk is basically water and deserves to be dumped down the sink so nobody has to suffer through it. He hates having to shop for clothes. But he has a thing for really cool bags, and, consequently, has more gig bags than guitars and a closet full of messenger bags and backpacks. He still misses his dog who was taken by cancer 5 years ago. Check out his Reverb shop and see if he has any gear he's trying to get rid of.
