Boss IR-2 Amp Modeller And Cabinet Iimpulse Response

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

Eleven solid platforms dish up every guitar amp flavor, from famous tube combos to vintage and modern stacks. There are also several original BOSS amps, including a high-gain Brown type derived from the Katana series. The amps are all paired with curated Celestion Digital IRs for dialing up polished sounds right away. 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.

With the IR-2’s intuitive interface, you’ll be ready to play in seconds. Simply select an amp type and tweak the sound with familiar amp-style controls. Then twist the Ambience knob to add some natural spaciousness and depth if desired. You can plug your other pedals into the IR-2’s input, just like you would with an amp. If you want to go further, use the send/return loop to patch mod, delay, and reverb effects into the chain after the amp sounds. The TRS return jack supports stereo operation, letting you pass stereo effects to the IR-2’s audio outputs.

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

Practice and Rehearsal
Connect headphones and enjoy top-quality guitar tones in every practice session, whether playing at home or traveling on the road. 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, allowing you to jam with songs from your music library and follow along with lessons from YouTube and other sources.

Stage Performance
Take the guesswork out of great stage sound and perform with consistent tones in every venue. Sending a feed from the IR-2’s outputs to a house PA system provides a studio-quality signal that’s not affected by the performance environment. And if you need more than one amp sound while performing, you can toggle between two IR-2 amp/cab setups with the pedal switch or an external footswitch.

Recording
Via the IR-2’s USB-C connector, send the sound of your complete rig directly to music recording software. Add tracks to full productions in a computer DAW. Or plug into your smartphone and capture inspiration on the move. You can monitor audio from the IR-2 and your software through headphones, eliminating the need to use a separate audio interface.
