1974 “Bud Box” MXR Phase 90 (not a reissue). These are rare and expensive but totally worth it for the vintage sound (e.g. The Rover, The Wanton Song, Breathe…) The modern Phase 90 sounds very different. That’s ok, unless you’re trying to recreate effects such as the songs listed. I’ll probably get another before I go back home as they’re much easier to find in the USA.
