Hello, I received a 1680 xpanded for my birthday in Dec. and shortly after purchaced 1 of the 2 optional effects boards. I have been totally through the manual and video, but cannot get any effect to work on anything I record. The effects work great on the demo songs, but thats all, I've asked for help from the store I got it from, I even took it to a freind who I consider very knowlegable on his 1680, and nobody can figure it out. Can anyone help me please, it's driving me nuts, thanks, Paul
