Hey, I've got a second H9 on the way. I need to get a really nice clean sound for a song that will be played at a wedding. It will be the song, hallelujah, and will be just the one guitar and a singer. I'd like to get some ambient stuff going on but still be able to hear the chords. I was considering something like classic crystals, then have a shimmer one the second one. I'm not very experienced with setting up ambient stuff though. Suggestions anyone?
