Boss IR-2 Amp & IR Cabinet Pedal | No Limit Guitar Co, Idaho Falls

The Boss IR-2 packs a full-featured amplifier simulator and IR cabinet pedal into the footprint of a standard BOSS stompbox — 11 expertly emulated amplifier models, from legendary tube amp recreations to BOSS's own Katana-derived originals, each paired with a custom-curated Celestion IR cabinet simulation. Running on 32-bit floating-point processing at 96kHz, the IR-2 delivers studio-grade tonal accuracy through a remarkably simple interface: four concentric knobs covering 3-band EQ, Level, Gain, and Ambience, plus a rotary amp selector — no screens, no menus, no learning curve. A USB-C port doubles the IR-2 as a 6-string audio interface for direct DAW recording, mono/stereo effects loops integrate your existing pedalboard, and instant A/B switching between two amp/IR combos via the pedal switch or external footswitch makes the IR-2 a genuinely complete tone solution that fits on any pedalboard.

Product Overview

The IR-2's 11 amplifier models cover an extraordinary range of tonal territory, and each one comes paired with a Celestion miked speaker cabinet IR custom-curated specifically for that amp model — the British-voiced Diamond model, for example, pairs with the sound of two Celestion Blue speakers, reflecting the kind of detailed, historically informed pairing that defines the IR-2's approach to tonal authenticity. The amp lineup spans from the Clean model — a pure BOSS original with full-range, natural, distortion-free tone — through the Twin (a legendary 2x12 combo with deep, colorful cleans), Tweed (a rougher, rawer 4x10 combo from the 1950s), and Diamond (chimey British Invasion-era cleans with aggressive bite). On the drive side, Crunch delivers a clear, hi-fi dirt punch, Brit recreates the roar of an iconic mid-1960s amplifier stack, and Brown — straight from the BOSS Katana series — excels at soaring, expressive lead tones.

For high-gain players, the IR-2's Hi-gain model offers smooth, articulate dirt-drenched tones as a BOSS original, while Sldn draws inspiration from a slow-sounding late-1980s tube amp renowned in the metal world for its flexible range of dirty tones. Modded pushes into the most brutal high-gain saturation BOSS has created, and Rfier recreates the amplifier that has defined high-gain heavy music for over three decades. This range means the IR-2 genuinely covers clean jazz tones, classic rock crunch, British stack roar, and the heaviest modern metal — all from a single compact pedal.

The interface is where the IR-2 distinguishes itself from virtually every other amp-sim and IR pedal on the market. Rather than navigating screens and menus, dialing in tone on the IR-2 feels like adjusting a favorite overdrive pedal — a rotary knob selects the amp model, and four concentric knobs control the 3-band EQ, Level, Gain, and a unique Ambience control that adds air and spatial depth to the overall tone. This tactile, immediate workflow makes tone-shaping fast and intuitive, especially valuable in live performance situations where reaching for a screen-based menu mid-set simply isn't practical.

Utility features round out the IR-2's professional capability. Mono/stereo effects loops allow modulation and time-based effects to be patched in directly after the amp simulation section — preserving the realistic amp-into-effects signal chain relationship that amp sims often struggle to replicate. The USB-C port serves double duty: connecting to a Mac or PC turns the IR-2 into a dedicated 6-string audio interface for recording pre-produced guitar tones directly into a DAW, and the same port supports loading third-party IRs via BOSS's IR loader app for players who want to go beyond the built-in Celestion IR pairings. A built-in headphone jack enables silent practice and recording sessions, and the pedal switch or an external footswitch allows instant switching between two fully configured amp/IR combinations — giving performers two complete tones available with a single click.

Ideal For

• Guitarists who want a complete amp simulator and IR cabinet solution in a standard pedalboard footprint without a dedicated amp sim unit
• Players who need studio-quality direct recording capability — the IR-2's USB-C audio interface function eliminates the need for separate recording interfaces for guitar tracking
• Performers who want instant A/B switching between two distinct amp/cab combinations via footswitch for live versatility
• Musicians who prefer a tactile, knob-based workflow over screen-and-menu amp sim interfaces
• Guitarists who want the flexibility to load custom third-party IRs alongside the included Celestion-curated cabinet simulations
• Players in Idaho Falls looking for a pedalboard-sized amp simulator that covers everything from clean jazz tones to extreme high-gain metal

Key Features

11 Expertly Emulated Amplifier Models with Custom Celestion IRs
From legendary tube amp recreations to BOSS's own Katana-derived originals, all 11 amp models are paired with custom-curated Celestion miked speaker cabinet IRs — each pairing chosen specifically to enhance the tonal authenticity of that amplifier's character.

32-Bit Floating-Point Processing at 96kHz
Top-of-the-line audio quality ensures the IR-2's amp and cabinet simulations sound accurate and detailed, with the headroom and resolution needed to capture the nuance of real amplifier and speaker response.

Four-Concentric-Knob Interface with Rotary Amp Selector
No screens, no menus — a rotary knob selects the amp model while four concentric knobs control 3-band EQ, Level, Gain, and Ambience, making tone-shaping feel as intuitive as dialing in a favorite overdrive pedal.

USB-C Audio Interface and IR Loading
The USB-C port doubles as a dedicated 6-string audio interface for direct DAW recording on Mac or PC, and supports loading third-party IRs via BOSS's IR loader app for players who want to expand beyond the included Celestion pairings.

Instant A/B Amp/IR Switching
Configure two complete amp/IR combinations and switch between them instantly using the pedal switch or an external footswitch — giving performers two fully realized tones accessible with a single click during a live set.

Mono/Stereo Effects Loop
Integrate modulation and time-based effects directly after the amp simulation section via the mono/stereo loop — preserving a realistic amp-into-effects signal relationship that's difficult to achieve with many amp sim pedals.

Built-In Headphone Jack
A dedicated headphone output enables silent practice and recording sessions without requiring a separate audio interface or amplifier.
