L.R. Baggs Voiceprint DI Acoustic Guitar Impulse Response Pedal

Create a Voiceprint that captures the one-of-a-kind voice of your instrument with a few simple steps

Guided by our AcousticLive™ app and proprietary impulse response technology, you can now use your smartphone like a studio in your pocket to capture a Voiceprint of your acoustic guitar. Developed with Dr. Jonathan Abel, co-founder of Universal Audio, our Voiceprint technology utilizes a sophisticated algorithm that intuitively measures your acoustic guitar by analyzing its actual timbre and playing response, then creates a customized preset for live play, as well as for direct recordings. Simply plug into the pedal and set your smartphone into position; tap on the bridge, strum a few chords, pick some strings, and you’re done!

Deploy anti•fb feedback profiles and shape your tone with powerful EQ

As an added benefit, every Voiceprint that you create identifies your guitar’s specific resonances that are prone to feedback and creates an Anti•FB profile to easily manage feedback with one simple control on the pedal. The app also provides advanced features, such as a graphical full-parametric EQ for balancing each preset to your exact taste. These features can also be used for creating enhanced presets, even if you choose not to apply a Voiceprint.

Sync your smartphone to the Voiceprint DI and unlock all of these great features

The AcousticLive app provides the processing you need to create your presets, while the Voiceprint DI is your live performance engine. With advanced processing at 96 kHz sampling, the robust playback algorithms provide studio quality performance designed for easy control during your live show. You can manage your presets in the app and store up to 99 instruments in your Voiceprint DI. The hardware is designed with a simple layout that includes the key features you will need for a successful show, but you can connect with the app during your live performance for additional functionality and control.
