TONE MATCH Gen2 PATCHES, CAPTURES, AND PROFILES OF OUR ’95 MESA BOOGIE DUAL RECTIFIER (REV. G)

For these patches, we’ve captured a ’95 Mesa Boogie Dual Rectifier 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 Dual Rectifier has become an iconic amplifier in the hard rock and metal genre of music. It is capable of huge rhythm and lead tones, and has been used on countless well known recordings and live tours. It is also a very versatile amplifier, capable of beautiful clean tones, as well as both vintage and modern voiced higher gain tones.
We’ve captured and tone matched the amp through a Mesa Boogie 4×12 Slant cab loaded with V30’s using a Royer 121 and Shure SM57 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, and Quad Cortex units)
The pack includes presets that simulate switching the channels on the amplifier, as well as a wide variety of effects.
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.
- AM4 presets include ‘Block Library’ files to give you access to dozens of different effects, all perfectly dialed in
- HX Stomp includes both the ‘A’ and ‘B’ presets, while POD Go includes a ‘JTM’ preset based on the 64 voice and a ‘PLEXI’ preset based on the 70 voice.
- 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 all channels (Clean, Orange and Red)
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 11 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.

This preset slays, a lot of my favorite bands and albums used the dual rec and its amazing to finally get that sound. My SG tuned down sounds amazing through this preset!

This capture sounds massive. I was searching for something that would help our band achieve a modern pop-punk sound and this preset delivers perfectly.

This Mesa Dual rec pack sounds really good especially the vintage mode captures. Pair it with a boost pedal and you get a good high gain Sound.

Sounds like a dual rect to me!

Great tones. I’m always looking for “the tone’ when using my fractal gear. This has it!
I’m still learning what this Dual Rec offers. THX!

Wow, what a blast to play! Those searing lead tones, that powerhouse crunch. I didn’t want to put my Les Paul down. Felt like a I had a Dual Rec in the room. This one is a beast! It sounds great on my Helix Floor. I imagine even better on the newer units. Love it!

Awesome amp tones – what a fun amp, and again, more massive than the stock Helix! I’ll use this for recording and I haven’t played it in church yet, but I will!
