I'm hoping to add tremolo to the toneprint slot on a TC chorus, or delay, or Viscous Vibe, or maybe a Dreamscape -- unclear to me if this is an option, and I can't ask Tor anymore!
You can't access the toneprint unless you have the pedal it was made/designed for - OR - you have the new PX5 which is supposed to have ALL of their toneprints.
So, yeah you'd need the Pipeline Trem. It's still available tho!
