Build:
very light and small factor yet very sturdy built design.
Sound:
Lots of boss (~100 of compressors, limiters, overdrives, delays, reverbs, modulations...) effects available in this unit which mostly sound great and with high fidelity also in terms of its A2D converters.
great accurate tuner.
Connectivity:
it has 3 loop for send/return of external effects which is helpful if you want to keep your loved effects in this small setup.
Controls:
it has preset mode and manual stomp mode.
for those working with presets it is very convenient but
IMO the manual mode lacks more flat/parallel controls as it basically has only 4 foot switches.
Although two more external control stomp switches can be connected and some controls can be multifunctional still as I mentioned for manual mode when no big display is available more stomp switches could be helpful.
Configuration:
the configuration is done basically using 3 rotating knobs and is quite simple yet not the most comfortable user interface comparing to other available units (Line6 for example...)
In this sense a BT connectivity for mobile app configuration could be very handy in real life scenarios also as the display is not huge.
Conclusion:
Small, high quality and durable build, HD sound quality, control and UI is more preset/scenario oriented, lacks some modern connectivity like BT and mobile app.
