Just want to throw out a third option for getting the Lexicon sound. (Let's call it easy way option 1b.)
Get a Digitech Polara pedal. Digitech is owned by Harmon audio, who also owns Lexicon. This pedal has true Lexicon algorithms in it. It's out of production, so not super easy to find, but easier than searching for vintage gear.
I have one but I'm very seriously considering selling it. I don't need the "Lexicon" sound for anything specific. I just got a HX Stomp & Helix Native bundle, and it has everything I need and so much more.
