TONE MATCH PATCHES, CAPTURES, AND PROFILES OF A ’97 MATCHLESS LIGHTNING

For these patches, we’ve captured a our Sampson-era ’97 Matchless Lightning. The result is a set of presets and captures that sound exactly like our amp, and the microphones, preamps, and EQ chains that we use to record it.
Our Lightning is a 15w 2×10 combo that reminds us of a great sounding AC15, but with Matchless’s distinct top end brilliance and chime. It will go from beautiful chimey cleans to awesome overdriven tones, and handles effects extremely well. A pair of Matchless Special Design G10 speakers give this amp some serious midrange punch as well.
We’ve captured and tone-matched the amp using a Royer 121 and Earthworks SR25 through a Neve 1073 DPX stereo 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.
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 an amp clone
CAPTURES & PROFILES
(Applies to TONEX, Quad Cortex, and Kemper units)
The captures increase through the entire gain range 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
You get a total of 6 captures
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.

The 2×10’s add that extra clearance for the bass notes! Sparkle and shine and that awesome Marchless tone!! Love it!

Another sunday, another superb tone. Set up the single coil first for service, it was cutting through so well, the bassist cranked up his Eden 410 to keep up. Everybody was feeling it as was I. It’s getting to the point, I have to make hard decisions as to what I want to use on any particular service. Thank you, Signal Theory for making the Bass player sweat
