First, a little about myself, history and usage. I'm not a pro. I'm a piddler. I've run the gamut of gear. From high end boutique tube amps, killer pedal boards, all the way back to the OG Line 6 Pod, Flextone, Behringer V-amp rig through tube power amps for live etc. I've played in original rock bands, playing in bars and I've played at my church. Currently I only exclusively do the latter as I've got a wife and 4 kids and a career so playing in a band is just not a priority right now. For the last 5 years of playing at my church I've run my pedal board with the usual suspects for this genre on it into the front end of either an Orange TH30, Matchless HC-30, Port City Pearl or 65 Amps Producer all into 1x12 cabinets, mic'd up with a 57 and a Cascade Fat Head mic. I've always struggled with getting the sound I hear coming out of the amp to translate well to what I hear in my in ear monitors and what comes out of the PA in the house for any number of reasons (my amp at home, backline at church, cab is in a small iso box not really treated well, mic placement variables, etc. etc.) So I decided to switch to DI in from a Helix to give me more consistency and flexibility in terms of effects routing in hopes that I could solve this problem. I chose the Helix mainly because the Kemper always seemed a little intimidating to me from what I had seen and I didn't really like the interface on either it or the Axe FX from what I had seen. The Helix, from the demo's seemed to be really good in that department. I purchased an Alto TS115A for home monitoring to help me get my patches set up at home as closely as possible to what they might sound like through the PA at church. I figured if I want to match a PA I'll run it through a PA speaker. First off, I never thought a modeler would give me the same responsiveness and feel of an amp. Man was I wrong. The Helix (for my taste) does it. The thing that's always been missing in modelers I've tried and used in the past was that "feel" and dynamic responsiveness. The Helix nails it. I'm beyond impressed by the quality of the amp tones, especially the low gain and clean tones this thing does. That's where modelers always seemed to really suck in the past and the Helix excels in that department. 2nd, I am super impressed by how good the OD pedal models are. Again, very real, very believable extremely usable. I'm not one to be pedantic when it comes to guitar stuff, I'm pretty much a pragmatist. Does the 808 model sound like an 808? I don't know. But it sounds good. And it is very usable unlike what I've experienced in the past with Line 6 modeled OD effects (mainly M series. Unusable). The other FX are also pretty great as well, but I'm used to that from Line6. They've always done well with mod/delay/verb stuff so I'm not surprised by that. 3rd. The interface is stupid simple. The default positions of all the amps and fx really seem to capture the "essence" of that thing, whatever it may be. In other words, if you want that classic "AC 30" sound from your amp, drop in the AC30 model and it's pretty much spot on with minimal tweaking. I find that to be insanely useful. For almost any OD, or amp model, I find I'm able to drop the model in, maybe tweak the drive a bit to taste and maybe adjust the treble control to suit my particular guitar and I'm 95% of the way there. Quick. Easy. No fuss, not hours tweaking and agonizing to get it just right. It just works. I love that. 4th. My "Alto Speaker as Home Monitor" setup worked like a charm. What I dialed up at home, sounded consistent and as expected in practice. I was very intentional about using the high and low cuts on the cabs (more on this later) to make sure I approached it more from "cab mic'd up to a PA" position than an "amp in a room" position and that worked beautifully. The sound guys said he had cut it a little bit at about 150 Hz and then a little notch in the 2.5k to 3k range which is pretty standard for guitar. Otherwise, he was very complimentary about it and really liked that it didn't have that "speaker in box" low/mid thing we're always having to fight with the current setup. 5th. I bought the Ownhammer Studio Pack of IR's. Huge upgrade. Line 6 cabs sound good. Ownhammer sound much better. More alive. More open. Totally worth the money. Finally: It did exactly what I wanted it to do. My IEM sound of my guitar has never sounded better. What I got in my ears is exactly what I heard in my house and what I had intended it to sound like. It was majorly refreshing. It DOES NOT sound like being in a room with a cranked amp. It sounds like a really awesome amp being mic'd up in a studio. And it does respond and FEEL like a real amp. That's what I love about it. Am I hard core in the modeling camp and swearing off tube amps forever?? No. But I will say, for the circumstances and the scenario that I'm subject to at this particular venue at this particular time, I believe I've found the best solution. If I was in an original band again, playing bars with an amp on stage and a floor wedge, I'd go back to my amp/pedalboard setup in a heartbeat. Tube amps are just fun!! Hope this has been helpful!
