IK Multimedia has just fired a major salvo in the portable guitar world, launching the TONEX Plug—their first-ever dedicated headphone amplifier for guitar. This pocket-sized powerhouse is set to directly compete with market leaders like the Fender Mustang Micro Plus and the Boss Katana:GO, boasting a massive library of over 40,000 amplifier and pedal models powered by the company’s acclaimed AI Machine Modeling technology.
The Tone Wars: IK Multimedia’s Ace in the Hole
While the physical form factor of the new TONEX Plug is familiar—a compact, screen-less unit that plugs directly into your guitar jack—IK Multimedia is betting its audio expertise will be the definitive difference.
The core feature that sets the TONEX Plug apart is its direct integration with the TONEX ecosystem. This means it utilizes the same sophisticated AI Machine Modeling found in the celebrated TONEX One and TONEX Pedal, translating to a level of tonal authenticity previously unheard of in this category.
- Unrivaled Tone Library: Players get access to over 40,000 Tone Model rigs (amp and pedal setups) via the ToneNET platform. This eye-watering number dwarfs the competition, offering an incredible breadth of digital rigs, from classic vintage amps to modern high-gain monsters, searchable by artist, song, or gear type.
- Pro-Grade Engine: The unit runs on the same algorithms as the professional-grade TONEX pedals, ensuring the digital models have the sound and feel of the original hardware.

Key Features and Competition Breakdown
Beyond the massive tone library, the TONEX Plug includes the essential modern features guitarists demand in a practice tool:
- Wireless Connectivity: Bluetooth compatibility allows for seamless streaming of backing tracks to jam along with.
- Recording Ready: The unit features USB-C connectivity, letting it double as a high-quality audio interface for direct recording on a computer.
- Built-in Tools: A chromatic tuner is included for quick setup.
- In-Depth Editing: A dedicated Tonex Control partner app offers precise fine-tuning of the signal chain, allowing users to tweak amps, cabs, IRs, EQs, and effects.
In terms of preset management, the TONEX Plug offers 30 user presets organized across 10 color-coded banks. This matches the Boss Katana:GO but falls short of the Fender Mustang Micro Plus, which offers a massive 100 user preset slots.

| Headphone Amp | Price (USD) | Max Tone/Preset Count | Key Technology | Connectivity |
| IK Multimedia TONEX Plug | $149.99 | 40,000+ Tone Models | AI Machine Modeling | Bluetooth, USB-C (Audio I/O) |
| Fender Mustang Micro Plus | $134 | 100 Presets (25 Amps/Effects) | Digital Modeling | Bluetooth, USB-C (Audio I/O) |
| Boss Katana:GO | $139 | 30 Presets (Guitar/Bass Modes) | Katana Amp Technology | Bluetooth, USB-C (Audio I/O) |
The new TONEX Plug is strategically priced at $149.99, positioning it just slightly above the Mustang Micro Plus ($134) and the Katana:GO ($139), aiming to justify the small premium with its overwhelming volume of professional-grade, AI-modeled tones.
The release of the TONEX Plug signals a significant step forward for the portable practice market, leveraging cutting-edge AI technology to give players an unprecedented sonic toolkit in a device small enough to fit in a gig bag.
