Reverse is like gate, only reverb volume increases from zero. I filled out the registration card for my Lexicon Jamman, subsequently I was phoned from the States by a guy called Greg to answer my questions. Later they sent me a large collection of information including Vortex and Jamman application notes. Manual is very brief, but there isn't much to learn anyway. Flanging and chorus are both good.
Plates are good.
For reverbs which are much better, spend twenty bucks more and buy the Reflex. Actually, the Reflex is better in all respects. If you want a new FX box, always choose the Reflex over the Alex, but if this is your best price option by a fair amount - it still beats alot of whats available. Selecting and editing are very simple and quick, this makes it simple to fingd the appropiate effect. The manual is short and allmost unnecessary.
