good day po.
i have a boss AC3 (acoustic modeller) when i use it, it produces this really loud and annoying HISS!
I use a Gator power supply and i also tried it with my Unoh power supply. the problem is still there. i tried plugging my guitar to another stomp trying to figure that maybe the HISS is because of my guitar, well its not.
i need help. if someone knows how to fix this please help. if you can refer me to people who can fix this, that would be a big help also. thanks very much in advance everyone
