zoom 505 guitar effects pedal

I've used the Zoom 505 and 505II and had pretty good results. They are a bit intimidating for those of use who are challenged by lack of understanding such things. I remember finding a users forum that listed a lot of information including patch combinations for the Zoom units! You mentioned playing "unplugged" so I'm assuming you've been primarily concerned with an acoustic guitar and wanting some electric effects? For my acoustic/electric I typically like a little reverb (usually from the amp), some chorus and delay to expand (fatten up) my sound...especially for fingerstyle playing...  That's pretty easy to obtain on the Zoom units...
