I bought a spark 2 amp last year, I love it. The other day, I was outside jamming on my guitar, my sister called, I went in the house and ended up talking to her all night, eventually told her I have to get off the phone I'm getting tired, and fell asleep. I forgot about my guitar and amp. Woke up the next morning to find them both still outside but it had rained in the evening.
It was luckily turned off all night. I immediately brought them inside, dried them off, and let them sit for a few days. I finally plugged things in this morning and turned them on. Everything powers on and lights up correctly, but no sound. I verified the guitar works by connecting to another amp, it works fine.
The only thing I can think of is the guitar cable is bad from being rained on, I will test a known working cable tonight. Or there is still water inside shorting something out. Or the water has damaged something.
Does anyone else have other ideas or experience from a mistake like this?
