Pro guitar sounds as takeaway

The IR-2 packs the inspiring sounds of classic tube amps and mic-driven speaker cabinets into a standard stompbox footprint, giving you easy access to studio-quality tones on quiet stages, flight dates, recording gigs, and practice sessions. Backed by decades of BOSS tonal expertise, each selection delivers the same expressive nuance and dynamic touch response of a real amp and cabinet. The sound quality is also top-notch, thanks to advanced DSP, 32-bit floating point processing, and a 96 kHz sampling rate.

Inspiring tones for every style

Eleven solid platforms cater to every guitar amp taste, from famous tube combos to vintage and modern stacks. There are also several original BOSS amps, including a high-gain Brown type that originated from the Katana series. The amps are all paired with curated Celestion Digital IRs, which deliver an instantly polished sound. If you prefer to use cab IRs from your own collection, you can load them into the pedal via USB-C and a dedicated app.

Instant sound

The IR-2's intuitive interface has you ready to play in seconds. Simply select an amp type and adjust the sound with the familiar amp-style controls. Then turn the Ambience knob to add some natural spaciousness and depth if desired. You can connect your other pedals to the IR-2's input, just as you would with an amp. If you want to take it a step further, you can use the send/return loop to add mod, delay, and reverb effects to the chain after the amp sounds. The TRS return jack supports stereo operation, so you can send stereo effects to the IR-2's audio outputs.

Play and record anywhere

Adding the IR-2 to your pedalboard significantly expands its versatility, giving you a complete guitar sound solution wherever you play.

Rehearsal and production

Plug in headphones and enjoy top-quality guitar tones for every practice session, whether you're playing at home or on the go. And prepare for upcoming shows with the same pedalboard setup you'll use on stage. Audio playback from a computer or mobile device is supported via USB-C, so you can jam along to songs from your music library and follow along with lessons from YouTube and other sources.

Stage Performance

Get a great stage sound and perform with consistent tones at every venue. By feeding the IR-2's outputs into a house PA system, you get a studio-quality signal that's unaffected by the performance environment. And if you need more than one amp sound while you're playing, you can switch between two IR-2 amp/cab setups with the footswitch or an external footswitch.

Recording

The IR-2's USB-C connector lets you send the audio from your entire rig directly to music recording software. Add tracks for full productions in a computer DAW. Or connect it to your smartphone and capture inspiration on the go. You can listen to audio from the IR-2 and your software through headphones, so you don't need to use a separate audio interface.
