The effects are all right out of the Helix series so if you are familiar with them and like the way they sound, you will be right at home. In my opinion about 90% of the bazillion effects Line 6 has are musical and useable. Some of the pitch stuff is still a little behind, but still passable for live use. They also include the "legacy" effects that are in Helix

The Flux feature looks promising but I haven't spent too much time with it yet. It's not as gimmicky as I was expecting I will say that. Editing is all done on the box and it's pretty straightforward. The preset management is well thought out. They allow you to limit the number of presets in the 'rotation' so you don't have to scroll through 128 if you only use 7. There is a Preset manager PC/Mac app that allows you to rename and reorder but not edit. I also like the versatility of the input/output options. It can be ran in line on your board in front of the amp, in mono 4 cable method, or you could technically put your drives in the HX One effects loop so it could be used before and after drive pedals on a direct to front of amp style pedalboard.

Most of the effects are usable as they are but editing is very easy. You can run just about all the effects in stereo which is nice.

By all appearances it's made very well.

I bought mine on sale, but even at MAP of $300 it's a great value. The HX series of effects is mature and stable and updated regularly. You are buying into a platform that has been proven over the last 8 years. The only comparable pedal I can think of is the Eventide H9 which is still twice the price and limited in other ways.

I've only dealt directly with Line 6 a few times over the last 20+ years and they were helpful. They also have a sponsored user forum full of people that are willing to help you out.

I think this pedal will best suit traditional pedalboard/amp users who could use a really good Jack of all trades pedal to fill out their sonic palette. If you already have a Helix or other digital modeler this really doesn't add much. The one exception might be an HX Stomp user who could use that one extra block for DSP heavy effects

I've been playing since the 70's and still kicking around in local rock bands because it keeps me young!

Rock, prog, CCM

Sound quality is good. the pitch shifting is still a little stiff compared to an H9 but for $250 or $300 it is good. Way better than the Plethora

Not midi clock transmit. You can not use it as a master midi clock despite it having a dedicated tap tempo... why? Not being able to save a preset in an off state is a deal breaker for me. Having to rely on the "FLUX" mode is ridiculous. I should be able to program it in an off state and I should be able to make the bypass button be momentary like my HX Stomp. I can't.

The sounds are good and I like that they threw in a solid noise gate in for free and don't count it as an effect.

It is a well made product, Yamaha makes solid stuff and Line 6 is no exception.

For live use it is not useable. In the studio it is a great Swiss army knife of effects.

Line 6 makes contacting them real chore.

This just falls short. Spend the extra money and get the HX Stomp instead. (It's twice the money but it is 10 times the product) It is way more usable and way more flexible. In reality the both take up about the same amount of pedal board real-estate.
