For those opting out for external looper, just an obvious remark that you need to have an external output device, compared to headphone output of Pod Go. I was quite dumbfounded having Pod Go + external looper at hand, and still not being able to loop conveniently without Yamaha THR (small practice amp) which I use just as a socket to headphones, how silly is that..
ps. What an implementation of the looper in Pod Go! There is a looper, but sometimes you cannot use it just because there are no more slots in the preset. Even if you're in luck, and there is a free pedal, you have to add it manually. Wow. Ok. That reminds of an old engineering joke, if you have a hammer at hand everything looks like a nail. If you have already "block" available in your design, let's model everything like one.
pps. Is there a way to rearrange pedals between footswitches, so that the mighty looper would stay at the bottom line of the foots witches? (Is it in the manual?) Ok, found the way to do it in the manual.
ppps. If only there was a screen available to display the current playing position within the loop. Or even blink some LED. Maybe we can add another block, loop position ;-)
