Boss IR-2

Take Your Signature Sound Everywhere

When using a regular guitar amplifier, getting consistent tones in different performance situations can sometimes be a challenge. With the compact and versatile IR-2 in your rig, you’re always ready to deliver your signature sound directly to a house PA or recording setup when needed. Choose from 11 premium amp types paired with Celestion Digital IRs and instantly tweak your sound via simple controls. Use the mono/stereo loop for post-amp effects and plug in headphones for monitoring and quiet practice. And with onboard USB-C, you can easily interface with music software and load in your favourite cab IRs.

Pro Guitar Sounds to Go
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.

Immediate Sound Creation
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.

Inspiring Tones for Every Style
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.
