I'm surprised no one has mentioned sending it back to the manufacturer. If it is not visibly damaged or beat up they may replace it. I have sent a few Spros back and the company replaced them no charge. There's no warranty expressly given but it is worth a try. Send megabass an email and see what they say.
Here is what their website says about warranty on their products:
