Response from developer
Hi there, Thanks for the review. It seems that you are using our app in "no headphones mode." The backing track will be slightly muted, as this allows the app to accurately detect your guitar playing without confusing it with the backing track of the song you’re playing. Regarding famous songs: when adding famous songs to your subscription, you will be refunded your initial purchase of £100 and then charged £150 for the new subscription, which includes the famous songs. Please don’t hesitate to reach out to us at app.support@gibson.com if you have any questions, comments, or suggestions. Best regards, Matthew
