PositiveGrid is running an interesting contest for their JamUp guitar multi-effects app. The grand prize is $150 iTunes Gift Card and an Alesis iO Dock, but everyone who enters automatically receives a $20 iTunes Gift Card! They would like for you to use that to upgrade to JamUp Pro, and still have some money left over for one of their expansion IAPs.
To enter, all you need to do is upload a video of you using JamUp (Lite, which is free, or Pro) and you're set. This is a really neat idea! It gets them more videos on YouTube and you $20.
The rules are straightforward:
Participants must make an original video demonstrating how far you're willing to go to win this contest. There are only three rules. Your video must use JamUp app (Lite or Pro), any interface is fine, and 1-3 minutes of run time.
This contest is running now through June 17th. For complete details and to submit your own video head over to their contest page.
I've never used this before, but I know Sean over at iOSMusician loves this one over all the other guitar apps.
