In my continuing quest for the Trower sound, I bought a used mini Deja Vibe (http://fulltone.com/miniDV.asp) thru ebay for $200. It just arrived so of course I gotta drop everything and try it out!  It works perfectly (I’ve never had bad luck on ebay) and sounds good, but I can tell that, like all effects, I’ll need to play with it a bit in order to understand how the the “right” sound out of it.
