*** Get into the Firecracker Atmosphere ***This is an amazing Firecracker soundboard.Shoot, wizzle, explode make all the sounds you want.Let it look like it is the 4th of July with this soundboard. Every party will be amazing when you play these sounds.Over 30 sounds.*** TROUBLE SHOOTING NO SOUND ***Make sure your mute is off and the volume is up. Look at the mute button, you should not see the red/orange stripe. If you still have no sounds playing make sure the mute button isn't set to "LOCK ROTATION". Change this in your settings.Good luck!
