Hey,
I recently got a Scarlett Solo 3rd gen and installed Helix Native. It sounds horrible. I tried multiple headphones, guitar cabs etc, the sound clean is fine but with overdrive it starts to become a huge mess. I will attach a sound clip. It sounds very fuzzy and terrible overall, not realistic at all. Here's the thing though, I am a huge fan of Helix and I know it sounds amazing so I know there is something wrong with my setup whether it's my DAW or gain staging or the physical unit (Scarlett Solo)...
Initially I focused on gain staging on basically felt that it sounded better with the input gain all the way down (on the inst input of the Scarlett) but the problem is that as soon as I would put an OD or crank the drive, the sound becomes terrible again. I tried low and high cuts. Tried different headphones and monitors. Used multiple guitars too to rule out a potential problem there too. The input gain on the Scarlett 3rd gen isn't like the 1st gen so it's not clipping at all. I play single-coils, not active pickups or anything crazy. I also monitor closely the peak input on the Native software and it never goes beyond -18dB so the problem isnt there either. I tried setting the input gain on the sotware to -20dB and it makes the problem go away somewhat but at that point the amps are no longer realistic since the input gain they see is so low.
What's strange is that it sounds good until there is a significant amount of overdrive but for example, the KOT that was recently added in 2.80 does sound like an Analogman KOT so I know that the software works.
Tried different DAWs (Cantabile Lite and GarageBand) with same results and made sure that I had no pluggins running on the track or the master.
I think it's something faulty with the Focusrite Scarlett but I'm a bit suprised since it's a well-know decent unit. It may not be as good as the Helix DI but it can't imagine that it could be this bad. The input impedance on the unit is rated at 1.5M ohms which is clearly suited for guitar.
Sorry for the terrible playing and sound and thanks for any help!
