Helix Amp Model Cheat Sheet: Which Block Matches Which Real Amp
Line 6 names every Helix amp model after the real amp it captures — but with pseudonyms that obscure the original. This is the complete decode: Helix name, real amp, starting gain, and character notes.

The quick answer: Line 6 uses fictionalized names on all Helix amp models to avoid trademark issues. The community has decoded all of them. This post maps every commonly used model to its real-world source, with recommended starting gain and a one-line character note for each.
Line 6 names every Helix amp model after the real amp it captures — but indirectly. "US Double Vib" is a Fender Twin Reverb Vibrato channel. "Cali Rectifire" is a Mesa/Boogie Dual Rectifier. "WhoWatt 100" is a Hiwatt DR103.
This naming convention makes legal sense. It makes practical sense for nobody. If you're new to Helix or switching to a new genre and want to start from the right amp, you shouldn't need to cross-reference a spreadsheet to figure out which block to open.
Here's the spreadsheet.
How to Use This
The Starting Gain column is a calibrated starting point for each model — not the only useful setting, but the position where the model most accurately represents the real amp's character. The percentage format matches Helix's parameter display.
"Character" is the one-sentence version of what this model is useful for. Consult the 10 Helix Amp Models You're Not Using post for deeper dives on the underused ones.
American Clean and Edge-of-Breakup

| Tweed Blues Brt | Fender Bassman 5F6-A (Bright) | 38% | Same amp, top-end shimmer — where Leo Fender was before Vox got there |
| US Deluxe Nrm | Fender Deluxe Reverb (blackface) | 30% | The room amp — clean headroom with gentle touch sensitivity |
| US Deluxe Vib | Fender Deluxe Reverb (Vibrato channel) | 30% | Slightly softer attack than Normal; where the built-in reverb and tremolo live |
| US Double Nrm | Fender Twin Reverb (Normal channel) | 25% | Maximum clean headroom; Robert Smith/Andy Summers territory |
| US Double Vib | Fender Twin Reverb (Vibrato channel) | 25% | Same headroom, slightly warmer; modern country clean |

| Helix Name | Real Amp | Starting Gain | Character |
|---|---|---|---|
| Essex AC15 | Vox AC15 | 42% | EF86 preamp warmth; less aggressive Top Boost than AC30 |
| Essex AC30 | Vox AC30 Top Boost | 45% | The jangle amp — Rickenbacker territory, The Edge's original platform |

Classic British Gain (Marshall-Derived)
| Helix Name | Real Amp | Starting Gain | Character |

| Brit J45 Brt | Marshall JTM45 (Bright channel) | 48% | Cleaner attack, more upper-mid definition; pairs well with a clean boost |
| Brit Plexi Nrm | Marshall Super Lead 100 1959 (Normal) | 52% | Classic crunch with sag; the Van Halen EVH preset starting point |
| Brit Plexi Brt | Marshall Super Lead 100 1959 (Bright) | 50% | Higher input sensitivity, tighter low end |
| Brit Plexi Jump | Marshall Super Lead (both channels linked) | 54% | More harmonic complexity; sounds "bigger" than either channel alone |

| Litigator | Fuchs ODS-50 (Overdrive Supreme) | 48% | Dumble-derived; the clean channel is as important as the drive |
| Optimo Grande | Dr. Z Route 66 | 45% | Organic, mid-focused tone stack; combines Fender and Vox qualities |
| Interstate Zed | Dr. Z M12 | 43% | More compressed than Route 66; great single-note sustain |

The Controls That Matter More Than Gain
When I built the comparison spreadsheet, I expected Gain to be the primary differentiator between models. It isn't. The two controls that do the most to make a model actually sound like the real amp — especially on clean and edge-of-breakup models — are Master and Sag.
Master: On most real amps, the master volume controls how hard the power section is being driven relative to the preamp. In Helix, the Master parameter affects the same relationship. Running Master too high on a clean model pushes it into compression that the real amp wouldn't exhibit. Running it too low creates a hollow sound. Start Master at 50% and adjust from there.
Sag: Controls the virtual power supply response — how much the amp "breathes" under pick attack. Higher Sag values add the bloom and compression of a rectifier-driven amp (Fender-style). Lower values simulate a stiffer, more immediate power supply (solid-state rectifier, like most modern Marshalls). The default isn't always right. For Bassman-style models, Sag at 40–60% is usually more accurate than the default.
What to Ignore: Hum and Ripple
The Hum and Ripple controls in Helix simulate the AC hum of an aging power supply and the 120Hz ripple from a poorly filtered rectifier. These controls serve a specific purpose — adding authenticity to studio recordings or capturing the character of a specific vintage amp. For live use or for general tone dialing, leave both at 0.

Key Terms
- Modeler
- A digital device that simulates the sound of real amps, pedals, and cabinets using DSP. Examples: Line 6 Helix, Neural DSP Quad Cortex, Fractal Axe-FX.
- Platform Translation
- The process of mapping a tone recipe's gear and settings to the equivalent blocks available on a specific modeler. E.g., a Fender Deluxe becomes 'US Deluxe Nrm' on Helix.
- Cabinet Simulation (Cab Sim)
- Digital emulation of a guitar speaker cabinet and microphone. Shapes the raw amp signal into what you'd hear from a mic'd cab in a studio.

Before the QC he ran a Kemper; before that, a Helix — he's methodical about his platform migrations the same way he's methodical about everything. He counts Plini, Misha Mansoor, and Guthrie Govan among his main influences, and he approaches tone the way he approaches design: systematically, with version control. He has two cats named Plini and Petrucci. The cats don't get along, which he thinks is poetic.
