I've got a nice assortment of effects, but for the sake of simplicity am thinking about trying the world of multi effects for live use. Having used a multi effects Line 6 model about 7 or 8 years ago, and still very happy with my Line 6 DL4 Delay Modeler, I'd be most likely to go with them again. Since I have no need for amp emulations, the M13 looks like the feature set I'd want. The only thing is, I see demos of the M13 on YouTube posted in September, 2008. That's almost three and a half years ago, an awful long time in the world of digital effects. I'd hate to make the fairly-expensive move on an M13 and have something new come out right away. On the other hand, the DL4 hasn't changed in a longer span and it's still being used by many, many guitarists. Any thoughts on this, or awareness of new Line 6 multi effects that may be about to be released? Cheers!
