OK those of you with guitar experience help me out... Due to the fact that my churhc has 2 bass players and no steady guitar players, I have volunteered to play guitar on the weeks I'm not playing bass. I'm played a little acoustic, but I'm hoping to branch into electric, to add more colors to the band on the weeks I'm not playing bass, and the semi-regular guitarist can be there. Let say I have a decent eletric guitar, and I want to get some effects for color. I'd rather do direct and not use an on stage amp, so could I use some kind of multi effects unit to get the colors I want? which ones are both good and affordable? If I went with individual effects, which ones are the most used or important?
