Compact device, easy to use. Perfect at first glance, to be seen over time.

Works very well with electric guitars but much less so with electroacoustics (tested with Takamine nylon, Martin and Taylor on Marshall and AER amps): hissing, various noises. It's a shame especially since Boss doesn't warn us about this incompatibility. Surprisingly, works very well with old Ovation electro guitars from the 80s!

It works perfectly.

Excellent

Super simple to install... What a freedom to no longer have wires. No latency or loss of quality. Very good battery life. A bit expensive but nothing to complain about, I recommend 100%.
