Love the idea of a looper, but I don't even know which end is up when it comes to them. What is the VERY easiest one w/the shortest learning curve? Maybe the Boomerang +? When will the 'Rang 2 be out, any info? How about the EHX 16-Second Delay (they're supposed to soon have a new model that eliminates the 4-count problem, I think)? Any opinions welcomed. Thanks.
