Well, my wife ordered the Koko Boost Reloaded and, it was DOA. It would fire up (by switching it to the on default, but the footswitch did nothing, regardless of whether it was battery powered, adapter, switched left/right/middle, nothing. I'm pretty bummed, as I had high hopes for it and with a 1 year old at home, my guitar time is pretty limited, which was wasted trying to get it to work.
I'm sure that I wouldn't have the same problem with an exchange, but for a "boutique" brand and price, you really only get one shot at it. So, off to try something else...will keep you posted.
