Japanese construction, sturdy-looking as that construction is a real gem for those who are tired of salsa dancing every time you want to change the sound (on / off 3 or 4 pedals both grrr ..).
Operating with connections in True Bypass there is therefore no loss of sound (except for cables between the pedals of course).
So very interesting when you have a whole collection of pedal, and best of all, it can also be used to change the channel on his amp: no more footswitch invasive and often of poor quality.
Very easy to use despite the manual in Japanese (...) there are several way of 'creation', and lots of connection options depending on its use (studio, live, guitar ---> two amps, two guitars - -> amp and much more).
Price level, I find it a bit expensive for what little it brings, let's say it is not essential in a set of pedals, but it is so convenient .. I think I will ever choose it anyway because I'm still lazy and once we arrived on scene it is placed, you use it and it's over (in case we use a pedalboard ready and since this is my case).
