TONE MATCH Gen2 PATCHES, CAPTURES, AND PROFILES OF OUR VOX AC15 HAND-WIRED

For these patches, we’ve captured a Vox AC15 Hand-Wired amplifier. 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.
The Vox AC15 has been a staple in the Vox lineage for decades, and is highly regarded among classic vintage amplifiers. It is not simply a lower wattage version of an AC30. AC15’s have their own character and tone. We find them to sound a bit thicker in the midrange, while still retaining the classic chime that Vox is known for.
We captured this beautiful hand-wired AC15 through a 12″ Celestion greenback 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, and Quad Cortex units)
The pack includes 2 sets of presets (each with SC and HB options). The presets feature different approaches to signal chain and/or amp channels.
A PRESET: The ‘A’ presets feature two amp blocks set up in a stereo pair with all the wet effects feeding into the amps. Think of it like running a large stereo pedalboard into two amplifiers set on the ‘edge of breakup’.
B PRESET: The ‘B’ presets allow to you increase the gain on the amp with a foot switch. You’ll see this switch labeled in the presets, and it is also programmed into the Snapshots. In the ‘B’ presets, the modulation, delay, and reverb effects are placed after the amplifier blocks.
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.
- POD Go only includes one set of presets because it cannot use stereo amp blocks.
- The HX Stomp presets do not include Snapshots.
CAPTURES & PROFILES
(Applies to TONEX, Quad Cortex, and Kemper units)
The captures increase through the entire gain range of the amp for the normal and top boost channels.
The Tone Model presets 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 9 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.










Kent M Dawson –
Wow – Just bought this for Tonex and this AC15 is really, really great. The cleans are nice and chimey – really does the VOX thing well. The TB drive captures are perfect for rythm and remind me more of a low watt plexi drive than an AC30 drive. The captures balance perfectly from clean to TB drive and take overdrives really well. I place an HXFX “Pillars” block in front of the AC15 TB 6 capture for leads and it just soars – smooth, nice harmonic response and good cut. Played these captures last Sunday morning and the FOH guy siad they sit in the mix perfectly and he didn’t really do much of anything to it (I had already applied a gate and some compression). This is probably my goto for now – the free AC30 and MARS captures I tries were good, but this AC15 is just over the top. Itching to try the Cold Water Canyon 🙂
