TONE MATCH Gen2 PATCHES, CAPTURES, AND PROFILES OF OUR MORGAN AC20 DELUXE

For these presets, we have captured our Morgan AC20 Deluxe. The result is set of presets and captures that sound exactly like our amp, and the microphones, preamps, and EQ chains that we use to record it.
The AC20 DLX is a high end boutique Vox AC30 inspired amp from Morgan. It features a 12ax7 channel and an EF86 channel. The 12ax7 channel is brighter and chimier, while the EF86 channel is thicker with more gain.
While this amp may be tonally related to an AC30, it sounds much more refined and polished to our ears. We think it’s a lot closer to a Matchless C-30, but it has it’s own voice and character. Our 1×12 cabinet has a Celestion Alnico Gold speaker, which is a great pairing for this amp.
We’ve tone-matched and captured the amp with a Royer 121 and Earthworks SR25 through a stereo Neve 1073 preamp.
TONE MATCH (Gen 2) PATCHES (Applies to Line 6 and Fractal presets)
These are part of our ‘Tone Match’ line of patches. To create these patches, we make custom IR’s that ‘match’ the HX and Fractal amp models to our real-world amp. The result is the Line 6 and Fractal units sound almost exactly like our actual amplifiers.
The ‘Gen2’ indicates a new process we’ve used when Tone Matching our amplifiers that takes more of the amplifier’s cab and speaker into account, resulting in a more accurate tone match impulse response.
PRESETS INFO
(Applies to Line 6 HX, Fractal, Quad Cortex, and Headrush units)
The pack includes fully featured presets designed for both single coil and humbucker equipped guitars. We’ve tone-matched and created presets based on both channels of this amplifier – the ‘EF’ patches are the EF86 channel, and the ‘AX’ patches are the 12ax7 channel.
SNAPSHOTS/SCENES
Our presets include Snapshots for instant access to a wide variety of tones, including clean sounds, ambient tones, driven, lead, and high gain sounds, and modulated tones.
NOTES:
- The HX Stomp, POD Go, and FM3 folders include ‘FX” presets. These presets include the additional effects blocks from the full Helix/Axe-FX versions. Because these units have signal flow and DSP limitations, they are not as fully featured as the flagship units.
- The HX Stomp presets do not include Snapshots.
- Headrush presets include amp clones of each channel
CAPTURES & PROFILES
The captures increase through the entire gain range of the amp for both channels of the amp.
The captures are numbered, and the number corresponds to the level of gain in the tone model. Lower numbers equal lower gain, and higher numbers equal higher gain. Typically a ‘2’ or ‘3’ is the ‘edge of breakup’, and is the perfect option to use with pedals
TONEX Captures:
These captures were created using the ‘V2’ capture process, which was introduced with Tonex Ver. 1.10. This means that these captures represent the highest possible level of accuracy, and are phase aligned with all other ‘V2’ captures.
Includes a total of 12 captures for TONEX
Capture Labels:
- AX = 12ax7 channel
- EF = EF86 channel
- MG = Morgan 1×12 cab
- Dir = Direct (TONEX only)
QUAD CORTEX/KEMPER
You get a total of 6 captures for Kemper/QC
QUAD/NANO CORTEX – HOW DO YOU GET THE CAPTURES?
When you place your order, we will need to manually send you the captures through the ‘Cortex Cloud’ app by Neural DSP, available for both iOS and Android devices. First, you need to have the app installed and you must have an account through the app (go here to create an account and access the app).
This is how we will send you the captures:
- Please include your Cortex Cloud app username in the ‘Notes’ field when checking out. If you do not include this, we cannot send you the captures. After we receive your order, we (SignalTheory) will follow you on the app.
- Follow ‘SignalTheory’ on the Cortex Cloud app. This will make us ‘friends’ through the app :). If you are not following us, we cannot send you the captures.
- After we receive your order, and we ‘Friends’ on the app, we will send you the captures through the app. We bundle the captures into presets, so you will receive one (or more) presets that include all the captures. You will find the captures in the ‘Shared with me’ section on your Quad Cortex.
- Please allow up to 5 business days for us to send you the captures. Most orders will be fulfilled within two business days or less. This fulfillment process must happen manually – we will do our best to get you the files quickly. Once the NDSP marketplace opens, this process may change.

These captures are great! Really clear and chimy, with a good amount of grit. I got the IR pack as well, but the presets with the cab sim in this bundle are really great. It’s my go to for my Sunday morning rig

Great sounding amp and IRs! They brighten up my humbuckers and I get that perfect snappy top end

Got this pack for the Line6 Pod Go and am quite pleased with it! Used it for a Sunday service and got the tones I was looking for (clean, driven, and ambient).
