Re: What else do I need on my board?
Welcome to the forum.
Your question is difficult to answer without some clues as to the styles in which you play.
Off the top of my head, I would suggest a second form of modulation - either phaser or Uni-Vibe. Since you appear to like Line6, they offer a modulation device in the same size as your Delay that models numerous Phasers, the U-V and, possibly, the Leslie cabinet.
