HeadRush Prime

The HeadRush Prime is a flagship guitar amp modeler and multi-effects processor aimed at guitarists, bassists, vocalists and live performers, built as a floorboard in a road-ready steel chassis¹. It carries over 600 amp, cab, microphone and effect models with advanced tone controls, plus downloadable rigs and tone captures, and it now has native Neural Amp Modeler support with direct TONE3000 access¹. Announced in March 2023 as the follow-up to the HeadRush Pedalboard, it builds on the Pedalboard's core physical design while adding vocal processing, including Antares Auto-Tune effects²³.

The controls: touchscreen, footswitches and expression pedal

At the heart of the Prime is a 7-inch touch display with what HeadRush calls its musician-centric interface: you create and edit Guitar, Bass, Key and Vocal rigs by touch, swipe and drag-and-drop¹. Guitar World described the interface as centering on that seven-inch touchscreen, with an expression pedal plus rotary knobs for physical control alongside the screen².

The 12 footswitches each have bright color-assignable LEDs and customizable OLED scribble strips that show each switch's current assignment and status for the rig in use¹. In Sweetwater's overview demo, Mitch Gallagher walked through the panel: three parameter controls that give instant access to parameters mapped to the selected on-screen item, a data entry scroll and enter control, a separate headphone volume, and a separate volume control for the aux input on the back panel⁴.

Scenes organize and simplify the rig, with lead, rhythm or customizable combinations of parameter changes available on a switch¹.

Power and connections

The Prime's rear panel covers a full live setup. There is a guitar and bass input, a combo XLR + 1/4-inch input with switchable 48V phantom power and an associated gain control for a vocal mic, and a USB A port for expanding storage with a flash drive¹⁴. The USB B port handles computer connection, data transfer and use as an audio interface for recording and reamping⁴.

Outputs are true stereo, with left and right XLR or 1/4-inch outputs that connect straight to a console, front-of-house or stereo cabs¹. In the Sweetwater demo, Gallagher described the main XLR outputs as a balanced signal you would feed to a full-range speaker system or straight into a DAW, and the two 1/4-inch outputs as usable at either amp level or line level⁴. The looper can sync to external MIDI devices like drum machines¹.

Neural Amp Modeler and TONE3000 support

The Prime now ships with native Neural Amp Modeler support and direct TONE3000 access¹. Through HeadRush Cloud, the Prime supports access to compatible NAM and TONE3000 content⁵. A firmware update in September 2026 brought NAM A2 support to the Prime, Core and Flex Prime, with the WiFi-enabled modelers supporting full A2 models⁵.

The polyphony depends on the capture type⁵:

• A2 Full: 2 captures at the same time, via stereo doubling, switch doubling, or 2 separate NAM blocks.
• A2 lite: 4 models in a single rig, between 2 dedicated NAM blocks.

Guitar.com's review of the NAM implementation on the Flex Prime, which shares the platform, found the hardware side of NAM A2 "pretty darn good" but noted a limit that also applies here: only one NAM model can be loaded per preset, whereas multiple stock HeadRush amps can be loaded, which the reviewer said may be a deal-breaker for some players⁶.

Prime versus Flex Prime

The HeadRush Flex Prime is a compact guitar and bass multi-effects processor and amp modeler that Guitar.com described as promising the same sounds and key functions as the stage-hogging Prime⁷⁸. The differences are mostly physical.

What reviewers said

Premier Guitar's reviewer found the touchscreen workflow approachable: navigating through the various menus and options is relatively easy, "a big plus for those hesitant to take the digital plunge"¹⁰. The same review tested the Amp Cloner with a homemade clone of a Zendrive overdrive, reporting that the process was very easy and that the Prime captured the essence of the pedal without much digital stiffness¹⁰.

In Sweetwater's demo video, Mitch Gallagher presented an overview of the Prime's features, sounds and workflow, covering the rear-panel connections, the parameter controls and the USB audio interface and reamping functions⁴.
