Hi Tony. I just checked my purple box and it is an AD-9. I think my experimenting is over. I've stumbled upon many cool/wild/interesting sounds, especially driving them with my 8-string! Besides being impractical, it cheapens the natural beauty of owning an Alembic, IMHO. Like I stated earlier, I lean towards subtly enhancing a bass's sound, not masking it. I usually jam with two guitars and drums...very LOUD! Before Christmas, one guitarist couldn't make it. I had THE MOST FUN as a three piece band! The sound blended quite well. My only effect was the VT Character Series with my 4-string Spoiler. I think I'll save the board for the 8-string Exploiter since I really like a bit of chorus/flanger with it. Man, I've got to learn to keep my posts short! Lloyd
