Welcome back Dave I use a Bespeco VM 18-L with the Vortex it comes from Italy it works just fine, I don't know how it compares to anything else. it sweeps full range every time the pedal doesn't travel very far physically, which is OK unless you wanted to pedal very quickly to an exact value and it's probably a bit cheaper Andy Butler Lexicon Vortex Database http://members.aol.com/soundfnr/vortex.htm
