HEADRUSH Multi-Effector | Features and Reviews of Each Model
HEADRUSH / Prime
- Intuitive interface with large 7-inch touch display
- Guitar/bass amps and effects + vocal effects (including Antares Auto-Tune® pitch correction)
- Equipped with Amp Cloner function that allows you to capture the sound of an amp pedal
- Supports cloud sharing via Wi-Fi and Bluetooth audio playback
- 12 foot switches (with color LEDs and OLED displays) + built-in expression pedal
The top-of-the-line model, HeadRush Prime, is a floor-standing processor that covers everything from guitars to vocals. Its high-performance multi-core DSP provides a huge library of amps and effects, realistic sounds, and even features an amp clone function and industry-standard Auto-Tune, making it a no-compromise in terms of functionality.
The 12 foot switches come with color displays and scribble strips, making them easy to see during live performances and allowing instant preset switching. Although it weighs about 7.6kg, it is large, but it also comes with input and output terminals for both guitar and vocals, and is described as a truly "amazing multi-function unit that can handle anything." It will be a powerful companion for intermediate players aiming to become professionals, and for players who play both guitar and vocals in band performances.
Positive reviews
- "The sound quality is overwhelmingly good. It's a cut above the BOSS ME-80 and Line6 POD Go I used in the past, and the built-in audio interface is convenient and perfect for DTM recording."
- "It's great that it has everything you need and can be used all in one. It's a flagship device that has everything from guitar effects to vocal effects."
- "The price is in the 17 yen range, which is reasonable for a flagship model, and I'm happy with the performance and price."
Negative reviews
- "It's huge. It weighs about 7kg, so you need to be prepared to carry it around."
- "The larger the device, the more expensive it is, so if you want to do everything, the Prime is the way to go, but some people say the price is a problem."
Pochip
HEADRUSH / Core
- Large 7-inch touch display and intuitive UI (same interface as Prime)
- Extensive effect/amp sound library for guitar + vocals (including Auto-Tune)
- Equipped with Amp Cloner function that allows you to capture the sound of your own equipment
- Supports cloud sharing via Wi-Fi and USB audio interface function
- Equipped with 5 foot switches (no expression built into the unit) *Can control wah, etc. by connecting an external pedal
"HeadRush Core" is a model that inherits the high sound quality and multi-function of Prime, but with a smaller, lighter board and a lower price. The sound engine and recording effects are almost the same as Prime, and it comes with a wide range of presets/models for guitars and vocals, and you can also use the amp/effect cloning and advanced practice tools.
The unit is compact and easy to carry, measuring approximately 40cm x 23cm and weighing 3.8kg, making it a good fit for users who find the Prime too large. However, it only has five foot switches and no pedals, so you will need to connect a separate expression pedal to control the wah or volume. It has a simple design that provides sufficient functionality but only the bare minimum of foot controls, making it a well-balanced model suitable for intermediate players who want high sound quality while still maintaining a reasonable size and price.
Positive reviews
- "The sound is so much better. If you switch from a similarly priced BOSS or Line 6 multi-effect amp, you'll be amazed at the difference in sound quality. The built-in audio IF makes it convenient for recording, and it's a big help from practice to live performances."
- "There are so many amps and effects, it's fun just to play around with them. Regular updates add more, so you'll never get bored."
- "It's not as big as the Prime, so it's easy to handle. It's also about half the weight, so it's perfect for me, who wants to keep my equipment compact."
Negative reviews
- "It's a shame that it doesn't have a built-in expression pedal. You can connect an external one, but some people say it would be more convenient to have one on board."
- "Some people have commented that they wish the price was a little lower. It has a full range of functions, but some people feel that it is a little pricey compared to competitors in the 5 yen range (such as HX Stomp)."
Pochip
HEADRUSH / Flex Prime
- Equipped with a 4-inch high-resolution touch display, intuitive UI for guitarists
- Equipped with the same DSP as the larger machines (Prime/Core), up to 14 blocks can be used simultaneously
- Includes over 600 amps, cabs, mics, and effects (including ChopTones presets and ReValver models)
- Equipped with Amp Cloner (clones and presets are compatible with Prime/Core)
- Wi-Fi compatible: Cloud sharing and remote editing from PC/tablet possible
- Compact housing with 3 foot switches and built-in expression pedal (with toe switch)
- Guitar input, stereo out, FX loop, MIDI IN/OUT, USB and other inputs and outputs
The latest model, HeadRush Flex Prime, released in 2024, is the ultimate multi-FX that packs advanced functions into a small size. While it has almost the same compact body as its predecessor, the MX5, the inside has been completely redesigned, and it has evolved so much that some user reviews say, "It looks similar, but the inside is different." Its biggest feature is that it is equipped with a powerful DSP equivalent to that of the higher-end model, and it has ample processing power even when using complex signal paths and multiple effects simultaneously for each preset.
The number of amps and effects included is huge, with over 600 types, which is about twice as many as the previous model MX5. It also has an Amp Cloner function and onboard Wi-Fi, and supports clones and rig sharing created by Prime/Core users, as well as the new "Remote Web Editing" function, making it a highly expandable platform. On the other hand, there are only three foot switches (compatible with the scene function) and the number of physical controls is minimal, but you can edit wirelessly from a tablet or PC, so you can comfortably create sounds at home by operating the screen. For intermediate players who want to use it for a wide range of purposes, from home practice to live performances, and who want to fit the latest technology into a small housing, the Flex Prime is a very attractive choice.
Positive reviews
- "The sound quality has more depth than the MX5. The already good sound has become even richer, and I'm very satisfied. It's like switching from a cheap audio interface to a high-end one, and even the lingering sound when you play is very pleasant."
- "The sluggishness of operation has been eliminated, and it now works very smoothly. There is no longer any slowness in screen operation like with the previous MX5 model, and it is comfortable to use. The functionality has also been greatly improved, so some people say that this one unit is enough for both home practice and home recording."
- "Despite its compact size, it responds wonderfully to your playing. The sound changes shades in response to the guitar volume adjustment, so it's great for playing with nuances at hand. Its small size makes it perfect for home or session use."
Negative reviews
- "It may be difficult to use only three foot switches when playing more songs at a live concert. It can be handled by creating a set list for each tone, but it has been pointed out that switching between foot switches becomes too busy on a large-scale stage."
- "It's unfortunate that the sound cuts off when switching presets (no spillover support). Although the delay reverb can be maintained within the scene function, some people are disappointed that the sound is cut off when switching between different presets."
Pochip
HEADRUSH / MX5
- Ultra-compact and lightweight (approx. 1.6 kg) with a 4-inch touch display
- 3 foot switches + expression pedal built-in (toe switch for wah/volume switching)
- Includes 46 amps, 15 cabinets, and 63 effects (with over 300 IRs)
- Supports gapless switching without interruption of sound when switching presets
- High-performance looper that can record up to 20 minutes and 24-bit compatible USB audio interface function
- Additional models will be added through firmware updates after release (Amp Cloner not included)
The HeadRush MX5 is a compact multi-effector released in 2021, packed with all the necessary features in a palm-sized case. Although production has been discontinued with the release of its successor, the Flex Prime, it is still available in stores and second-hand, and is a firm favorite among budget-conscious users. It has been praised for its overwhelming ease of use with touch panel operation and its top-class analog-like sound in its price range, with some store clerk reviews saying the sound quality is so good that they are amazed, asking, "What kind of sound can you get at this price?"
However, compared to the latest models, it has fewer amps and effects and does not have Amp Cloner or Wi-Fi sharing functions, so its functionality is limited. Still, it has all the basic functions of a guitar/bass multi-effector, and many people say that the sounds it comes with are of a quality that is good enough for practical use. For intermediate players who want to get a good sound easily and at a good price, there may be some merit in choosing the older MX5 model.
Positive reviews
- "I think it's the easiest to use and produces the most analog sound in this price range. The presets are well thought out and you can use them right out of the box."
- "The salesperson commented, 'Wow, this sound for this price?' They were amazed. It doesn't have the poor distortion that is common with cheap multi-effect pedals, and it's a quality that makes it fun to play."
- "The touch panel allows intuitive operation, so even first-time users won't be confused. There's no need to worry about button combinations, and anyone familiar with smartphones and PCs can get started creating sounds right away."
Negative reviews
- "There is some noise, but if you process it in your DAW, I think it's not a problem. Some people say that in exchange for the raw, analog-like sound, there is a slight amount of noise."
- "Compared to its successor, the Flex Prime, it is inferior in terms of the number of recording models. However, some people say that the MX5 is enough considering the price difference, so if you are willing to compromise, it will not be a disadvantage."
