Voiceprint ® DI
AcousticLive ™ App
 Resources 

Any pickup system can be used with the Voiceprint DI, active or passive. However, in cases with poor string balance or an improper installation, the Voiceprint will reflect those issues.

Any acoustic instrument with a pickup should work with the Voiceprint DI. The default settings are optimized for steel string acoustic guitars. However, many other instruments will work just fine with these default settings.

The Voiceprint DI should go at the beginning of your signal chain so that your guitar is first into the Voiceprint before anything else. Use the effects loop or 1/4" output for effects/pedals such as compressors, reverb, delay, chorus, and saturation

The VPDI and AcousticLive App are designed to use the predictable frequency response of the iPhone mic to accurately measure your instrument's unique character. As a measurement tool, the phone mic has more reliable results than most external mics.

The VPDI is designed to reduce the need for additional gear. However, if you want to try external mics, the system will work with them. Your results will be colored by the specific tone of those 3rd-party microphones and the results will vary.

The Voiceprint DI will not run on batteries or phantom power. The included power supply should be used for best performance.

The included power supply should be used for best performance and should be isolated or separate from the power supply for other pedals. In some cases multi-output power supplies such as power-brick style supplies can work well but in some cases they cause unwanted power supply noise.

The app is required to create Voiceprints, make EQ changes and use the Advanced Toolkit (in-app purchase).

Without a phone connected, the user will still have access to all the controls necessary for live performance including VP blend, AntiFB blend, phase, PAD, volume, mute and scrolling/selecting presets. These can be done directly from the Voiceprint DI pedal.

Each Voiceprint is created from your guitar's unique voice and from the pickup you have installed. Using a VP made on one guitar will not yield reliable results on any other instrument.

Like any microphone, the phone mic will capture different aspects of the guitar's voice with different placements. However, the general mic placement outlined in the in-app tutorial will produce the best results for most players. If you alter the mic placement, the resulting Voiceprints will reflect those changes.

No. Only the files created with the AcousticLive app are supported at this time. The goal is to capture your specific instrument and pickup to give you your guitar's unique voice. That cannot be done with a 3rd party IR import.

The Voiceprint DI pedal can store up to 99 presets. The Preset Library on your phone does not have a preset limit. There are advanced management features in the library on the app to help you create playlists to manage different gigs or set lists if you want to explore them.

No. The VPDI does not have a tuner or effects.

Yes. AcousticLive is available for both iOS and Android.

No. The app updates are independent of the pedal firmware updates.

This is up to user preference. Some players have found that different settings work better for certain playing applications. You can also use the same Voiceprint in different Presets if you want to alter the EQ or other settings and save them separately.

The VPDI allows the user to set the volume level of each preset individually using the Preset Level control in the LEV module.

AcousticLive does not currently have a dedicated iPad app. The iPhone version can be downloaded and used on most current iPad models but will visually not fit correctly on the screen. Voiceprints can still be created using the iPad.
