Handy Guitar Lab for B2 FOUR

I had hoped to be able to get a little preview of what it looks like, what patches are available and what additional effects might be available (as pre-purchase research). However, without a device connected it doesn't do anything. Understandable, but it would be cool if they had an "Offline" mode to mock things up. I get why they don't though.

Too bad we have to pay for this app :(

The app lets you control the device from your phone, including editing patches. But it doesn’t let you back up and manage your patches, nor does it provide access to patches developed by anyone other than Zoom. Personally I don’t find it easier to edit patches on my phone than on the device, and given that the phone must be connected by a short USB cable it’s not practical for using on stage.
