If I know Rob, those are Pyramid Gold Flats... a classic Alembic sound; Series I bass strung with Pyramids. Hard to mess one up, but that's a great combination. The next nice thing is, changing to an alternate set is a 5-minute job on an Alembic. I do this with my old Distillate from time to time... I keep a set of TI Jazz Rounds in the case ready to go on there, but ordinarily she wears flats. Had Pyramids on there too, for a while.
