Power to spare

Line 6 spearheaded the modeling revolution years ago. Now they step into the future with Helix Rack. Helix Rack's brain is Line 6's dual DSP HX modeling engine. Representing a giant leap forward in guitar technology, the HX engine reproduces every minute detail that goes into a great amplifier. Guitarists at Sweetwater know that feel is important to most players, and every single aspect has been taken into account, down to an amplifier's power supply ripple and tube sag, ensuring you receive an ultra-realistic playing feel and experience. The classic bloom and compression of some amps and the powerful punch of others are all faithfully accounted for. And you can also load custom impulse responses to personalize your tone.

Up and Running in No Time

Before Helix Rack, powerful amp and effects modeling often came with a significant learning curve. But even with a massive amount of routing, recording, and editing power under the hood, Helix Rack's workflow is incredibly easy to learn. And the large 6.2" LCD display rids the system of all the menu surfing while giving as much control as the deepest editing software. It's so intuitive to navigate that Line 6 claims you'll have 90% of Helix mastered with a five-minute glance at the full-color Helix quick start guide. And we're not just talking tone editing. The four stereo paths per preset allow for all sorts of routing setups. You can design your rig at the speed of thought.

Give Helix the Control

Already have a beloved guitar rig that you've spent years getting just right? Helix Rack also makes a robust controller for your rig. It allows you to easily create a hardware/software hybrid setup integrating your other pedals, your channel-switching tube amplifier, rack equipment, and even other instruments, offering you one of the most in-depth routing I/O on any guitar processor. And you do it all through Helix Rack's four stereo effects loops. You can send multiple wet and dry signals to different sources, place the loops in various locations in your signal chain, swap between your amp and modeled sounds, and so much more. You can even take control of your band's MIDI rig with up to six separate MIDI commands at patch recall.

Helix Rack

The Helix rack is an amazing piece of gear. Well worth the money. Very comfortable in the company of the Kemper profiler, Axe fx. The Helix rack actually sounds and feels like the amplifiers and effects that it emulates. I remember my very first effects processor in the late 80s early 90s was a DigiTech valve Fx and this thing is light-years beyond what processor is used to be. Very very satisfied and would definitely recommend coming from a professional musician. I also bought the Helix LT floor model. Buy with confidence you'll be glad you did. And it's always a big shout out to my salesman Doc, who always does an outstanding job and taking care of my needs always above par and top shelf.

Love the tones and flexibility

Was worried a little bit pulling the trigger to buy this unit. I have a POD X3 Pro, HD500 Rack and HD500x pedal board. I wanted to get back to having a rack unit and when I read about how flexible this unit was with the 4 send return paths and the ability to have 3 expression pedals attached to it, I figured what the hell. Going from the POD computer editing to the Helix was a bit of stumbling point at first but now I love it. The tones I'm getting are much better than I was with the HD500x and the with the floor control I can have patches now that can comprise all the parts for a song that I need. No longer to I have to have a separate patch just for the acoustic part or the tuning change. The snapshot feature is wonderful. I like how you can even on the fly edit your pedal settings as you play. It is sweet being able to read the displays without my glasses and name the patches as well as the snapshots so they make sense, change the color of the buttons so you can quickly see what but it what just by the color. If you get one please take the time to read up on how to do the editing and get on the forum and read what everyone says about how to setup your patches so they will get the best tone for you. Oh yeah the IR's are so much fun to play with. Almost too many options at times, but very easy to find some patches built in or online and get playing quickly. I run mine through a 50w per channel tube power amp and love the harmonics I get out of it. Everything from sweet clean tones to the most heavy 7 string tones you could want.

Line 6 Helix Rack

Yes, 5 stars... that's right! I've been playing in several cover bands ranging from artists like Elvis to The Black Keys and have been continually searching for "The Perfect Tone". Prior to the Helix I was playing a Marshall JVM410h with 4x12 vintage 30's through a Boss GT100 via the 4 cable method. Was I disappointed... no, I mean its a Marshall tube amp so of course its great, but I was tired of lugging around all my gear and then spending another 30 minutes to set it up. So after much research I opted for the Helix Rack with floor controller and I'm now about ready to sell all my Marshall gear! The design and construction of this product is superb and the overall look is great. Initially I was not impressed with the factory tones and thought maybe I had made an expensive mistake, but after spending some time with my nose in the online manual and tweaking the dials I have found musical heaven. Never has my guitar sung so beautifully... the clarity... the tonality... the crispness are all wonderful. The Helix has renewed my vigor to shred and I am looking forward to watching jaws drop at the next gig! Get Yours... Period!

Helix Rack and Helix Control

I don't usually do reviews, but this deserves it. Had given up with the POD HD 500 and went back to using tube amps, kept reading the reviews and watching videos of the Helix so thought I'd try it.OMG-Line 6...night and day from the POD HD stuff !! The Helix SOUNDS SOOOOOOO GOOD ! And is so very easy to adjust and program, THANK YOU Line 6-OUTSTANDING JOB. And for the price it can't be beat, for less than the price of just the "UNIT" of the competition, you have the Helix Rack and Control (which is also outstanding btw), so everyone complaining about it being expensive...just shut up and look at something else. Anyway, I AM VERY IMPRESSED !!!!!

Outstanding Gear

Worth the money but doesn't play well with others!!! By that I mean other Line6 gear!! Not fully integrated with the DT series amps!! Despite the VDI only marginal interaction with your Variax (can't interface with Workbench?????????? Needs FRFR speaker to really get full audio value. Another piece of advise-- Don't buy this model (Rack) without the Helix Control foot controller. You really need this to get full function of the Rack unit.
Music background: Lunatic spender of major bucks on Music Gear. Owner of way too much to be healthy!!!

Sweetwater Advice

Connor Smith

The Line 6 Helix Rack is my go-to guitar effects processor. Being able to take it from my home studio to my live rig is extremely convenient, but the greatest thing about the Helix Rack is how quickly it lets me reach the sound in my head. The simple layout also makes saving and organizing my custom presets easy. On top of everything, I love that I can download and save impulse responses for a limitless range of realistic tone.

Line 6 Helix Guitar Multi-effects Processor

Helix is an extraordinarily powerful recording and performing tool. It rivals pricier modeling products and surpasses them in some regards, especially with its large, bright, and color-coded editing surfaces. The design is sleek and the construction is genuinely roadworthy....
