So i just got my h9 and while trying the app i accidentaly spent my coupon on phaser effect. I didn't mean to purchase it. Is there a way to return the phaser effect and spend my coupon on something else?
If you haven't used the coupon, yes, the coupon will travel with the stompbox to the next owner. If you have used the coupon, no, the algorithm is already tied to your account.
