USE

Editing sounds very comfortable, but they turn 4 buttons are very sensitive ...

SOUND QUALITY

The effects are of a good quality there doing their jobs (aside the step phaser, they are a bit craqu in marshall !!)

NOTICE GLOBAL

Super good stuff, solid anyway ...
The effects are good qualities and the whole forms a nice ensemble (and cheap) for those who do not want to take a gas plant type crankset Boss GTX while being under foot some modulations ...
I do not use too much the usual effects and I do a test with this pedal but it suits me perfectly yet ...
