simple et super efficace !

Easy to use, both for connecting 2 guitars to the same amp (this was my main intended use for a concert) and for connecting a single guitar to 2 amps. Sound quality is consistent. Moreover, no real need for power supply (which is a plus for forgetful people, but it only lights up the LEDs - without powering it on, it still works). Also, the casing and buttons are sturdy. Personally, I find the price a bit high (not related to Woodbrass but to Fender).

a battery cover screw spins freely, otherwise it's fine

It's so cool to have the sound on 2 amps at the same time or separately!

Simple, efficace, robuste!

Does the job of connecting 2 guitars to an amp except if a guitar is connected with a wireless system!!! Too bad
