The Helix is unbelievable.
This is hands down the best money I've spent on guitar equipment.
Sounds amazing, and has very flexible inputs/outputs.
The Helix has many options to built a good tone , it is complex and you have too keep that in mind when you buy one. Because it is complex you can easily build tones but to build good tones you might actually stick some time to it , to learn the way you properly use it but after you do , you get very good tones , especially for Modern metal genre.
The feature are way more then enough. The Quality is SOLID. you can rest assure nothing will brake easily , all you have to care about is the screen , but there are many screen protectors you can buy on the market. Compared to a Kemper , this is way better in my opion since you can manipulate the sound you want way much better.Line 6 also has a pretty active community and a site for sharing patches. The other day, I heard a song, and was pretty intrigued by the sound on the guitar. I watched a video of the band to see what he was using for an instrument (Les Paul) and then went to line 6’s site and searched for the song in the presets archive. Sure enough, grabbing the preset from the archive and plugging in my Les Paul, bam, I’ve got the sound.
This is 10/10 guitar processor, hope you enjoy it !
