TONE MATCH Gen2 PATCHES, CAPTURES, AND PROFILES OF A JMI 30/6 TOP BOOST

For these patches, we’ve captured a JMI 30/6 Top Boost 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 first Vox’s ever made were produced by the Jennings Musical Instrument Company (JMI). Over the years, the ‘Vox’ brand has been owned by various companies, but the JMI brand has been resurrected, and they’re making faithful re-creations of the coveted 60’s Vox amplifiers. Our 30/6 Top Boost is a beautifully made re-creation of a mid-60’s AC30 Top Boost.
We captured 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, and Quad Cortex units)
The pack includes 2 sets of presets (each with SC and HB options). The presets are labeled ‘Br’ and ‘Nr’, and feature different approaches to signal chain and amp channels.
‘Br’ PRESETS: The ‘Br’’ presets feature the Brilliant channel with 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’.
‘Nr’ PRESETS: The ‘Nr’ presets feature the Normal channel. In the ‘B’ presets, the modulation, delay, and reverb effects are placed after the single (mono) amplifier block. This replicates a studio setting where all the modulation, delay, and reverb effects are applied after the amplifier.
NOTE: 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 and POD Go presets also have a Vb and Nr template, but with limited effects. POD Go’s signal chain is much more limited, so the delays, reverbs, and modulation are placed after the amp block.
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.
NOTE: 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 including the Brilliant, Normal, and Jumpered channels. We’ve delivered 9 total captures across all three 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.
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.

ac30 on steroids, love it

Hallelujah. At last, an AC-30 capture that sounds like the real thing. I’ve owned several AC-30s over the years and this one comes closest to the older 1960s models.
