| The Line 6 Delay Modeller is a  great 
choice for affordable looping, but your Yamaha SPX90 (if 
it's the Mark II) has 2 seconds of delay, long enough to build a phrase (albeit 
a short one).  In my opinion, 2 seconds is just 
about where looping begins. Where does it end?  And 
something else begin?  When your significant other gets tired of 
it. Gary |
