If you have Darkglass e500 amplifier, then it’s a must.
The only drawback is the necessity to use also USB-C cable in order to get the amplifier presets (when changed in app) synced with pedal, but once done, it’s not needed anymore, i.e. for gig.
Appreciate the long MIDI cabel (included) and no need to use external power, when connected to e500.
For the very first initial setup, PC or MAC is necessary, it can’t be done via phone app. But it’s needed just once.
