The new Headrush Flex Prime is a compact, all-in-one Amp simulator and Multi effects processor designed for live performance, studio recording, and practice. With Headrush Flex Prime, you get a wide variety of high-quality, ultra-responsive and realistic guitar effects, amp models, cabinets, and microphone emulations. For connectivity, FlexPrime includes a 1/4” guitar input, an external expression pedal input, two 1/4” TRS outputs, a 3.5mm headphone output, an auxiliary input, MIDI in/out, and a 1/4” stereo effects loop for external pedal integration. A USB-C port is provided for firmware updates, file transfers, and for using Flex Prime as a 24-bit audio interface.
The Headrush Flex Prime is the most compact model in Headrush’s second-generation lineup, following up on the first generation Headrush MX-5. Like the second generation Headrush pedalboard and Headrush CORE, the user interface on Headrush Flex Prime has been extensively redesigned with a new icon-driven menu layout.
At the center of the Headrush Flex Prime interface is a four-inch high-resolution touchscreen which serves as the main hub for navigating menus, editing rigs, and accessing various features. Flex Prime has the same DSP capabilities as the larger Headrush Prime and Core models, supporting up to 14 effect blocks per preset with multiple signal paths. Compared to the larger Headrush Core and Pedalboard models, the Flex Prime’s screen has a reduced number of physical controls, but the processing power and internal sounds and effects remain identical. A large main knob allows for quick overall volume adjustments while a rotary encoder facilitates scrolling through menu options and adjusting parameter values—a press-to-confirm function streamlines the editing process.
Using the Flex Prime is easy and intuitive, with the touch screen displaying essential controls such as the input block, signal chain, and output block details. Users can view the selected rig name, footswitch assignments, and signal path visualization while accessing practice tools: a tuner, metronome, looper, firmware updater, global EQ, and much more. The top menu bar shows CPU usage, Bluetooth, Wi-Fi status, and rig name. Users can switch rigs by swiping down and selecting via the touchscreen or encoder knob.
Creating a new rig is as simple as selecting the “New Rig” button and customizing the signal chain. The hardware assign button allows you to rearrange effect blocks within the rig or create scene-based configurations. Changes can be saved as new rigs or updated within existing presets.
For hands-free control, Flex Prime includes three footswitches that can be assigned to activate or deactivate effects blocks, scenes, or load factory or user created patches. Holding these footswitches grants access to additional functions such as changing footswitch modes, opening the looper, or activating the tuner. An onboard expression pedal further enhances playability, allowing dynamic control over various parameters such as volume or wah effects. These physical controls, combined with the touchscreen interface, provide a comprehensive and flexible platform for creating, editing, and controlling your rigs.
Flex Prime comes bundled with Headrush Amp Cloner and ReValver 5 software for macOS and Windows for precise audio cloning of amplifiers, distortion, overdrive, and other effect pedals. Using the new Headrush Super Clone feature, you are able to combine multiple amp or pedal clones in a single patch. Using the Headrush Flex Prime scene feature, you can assign multiple clones or super clones to one of the three footswitches. Additionally, the included ReValver Live software enables you to utilize your cloned gear in your DAW, integrating seamlessly with Headrush’s FX library and third-party impulse responses (IRs).
FlexPrime also offers extensive looper and performance capabilities, including up to five minutes of looping time with 20 minutes of overdubs per loop. Additional performance tools include a global EQ, multi-assignment footswitch functionality, and tools for creating and managing your setlists.
The Headrush Flex Prime, Core, and Prime boards come equipped with four brand new built-in synthesizer effects: Hybrid Synth, Electric Piano, DB-33 Organ, and Ambient Verve. These effects utilize Headrush’s proprietary real-time polyphonic Pitch-to-MIDI tracking, allowing your guitar to be transformed into a wide variety of expressive synth sounds.
To enhance your workflow, a new Remote Editor tool enables full rig customization from a laptop or tablet. Connecting to the Remote Editor involves linking the Flex Prime to a local network, navigating to Global Settings, and accessing the tool via a web browser. The interface includes several key features: the Edit Rigs Window, which organizes and categorizes user-created rigs with search functionality; the Setlist Window, which manages performance setups; and the Global EQ Window, which allows adjustments to system-wide frequency response.
Summing it up, the new Headrush Flex Prime delivers professional-grade sound processing power in a portable form factor, combining intuitive touchscreen control, advanced amp modeling, and seamless cloud integration. With powerful editing tools and versatile connectivity, it is an ideal solution for guitarists and bassists looking for an all-in-one effects processor for both live and studio use. The Headrush Flex Prime is a perfect size solution for your gig bag, and it’s easy to load up a handful of your favorite tones and craft those into usable set lists for desktop recording and live gigs.
Headrush Flex Prime is available now for $499.
