  • Famous Moments and Jimi’s Gear

Take a trip through Jimi's monumental rock & roll history and the gear that defined it all with Famous Moments. Choose a specific amp or pedal from one of our official presets to get a taste of that piece of gear's unique tone. Access Famous Moments by tapping on the banner in the Music page!


  • Auto Tone

Jam along with your favorite Hendrix™ songs and Spark will display chords and even switch presets for you, automatically. To access the songs that include this feature:


1. Go to the Music page and tap on the Experience Jimi Hendrix™ banner at the top of the page.

2. You may access the songs that have Auto Tone enabled by:

    • Going into any of the articles featured in Famous Moments and scrolling down to the bottom of the page
    • Going into any of the articles featured in Jimi’s Gear; if the gear was used in the creation of the tone for a song with Auto Tone enabled, it will show up at the bottom of the page
    • Playing any of the songs listed at the bottom of the Experience Jimi Hendrix™ page under Auto Tone

3. Tapping into the song, Spark will take a few seconds to load the presets. Once all the presets are loaded, the song will begin to play. Play along with the song and once the red circle on screen becomes connected, the next tone will be loaded.

4. To turn off Auto Tone, tap the Auto Tone slider at the bottom of the song detail page, or if you’re on a different menu, tap the X on the right side of the global player at the bottom of the screen to close the song and revert to your previously loaded preset. You may also turn off Auto Tone from the amp control menu.


How to Purchase:

You may purchase the expansion pack directly from the app. Tapping on any of the amps or effects included in the pack when you have not purchased it will bring a pop up to purchase.

You may also tap on the banner located in the Music screen to purchase the pack. The license will be linked to your Positive Grid account, so please make sure to purchase the expansion pack after you’ve logged in to your account.
