Old thread, but I'm dithering over the Solo XT and the RC-3... and the Ditto X2... did I mention I was dithering? Found this comment on an acoustic forum: "...one advantage that the Digitech pedals still have over the Boss offerings is a flexible time-signature function. With the Boss pedals, when you use the rhythm functions for looping, you can only make loops in 4/4 and 3/4. The Jamman allows you to work with anything from 2 to 15 beats per measure, and it will quantize those for you just like it does with the default 4/4." I'm trying to decide if this is a deal decider, given that I'm a 'bedroom' player with timing that's, let's say, in need of improvement.
