Fender MGT4 Footswitch

First of all, I use this on an Acoustic Junior GO amp, so my rating is based on the experience with that amp.
This product is solid and sturdy, looks like it will last forever.
The controls are simple but:
The FX Bypass works only on the active effect and selecting a new effect will instantly turn off the bypass. I find this uncomfortable, because I may need to scroll a few effects to get the one I need and it'd be much more rational to have all effects bypassed until I deactivate the bypass.
Scrolling the effects with a single button is not the best feature, especially when for example you have to switch between Echo and Hall Reverb, since Echo is right after it. You basically have to tap too many times and doing it live while you're playing is terrible, especially because the FX Bypass won't help you to avoid all the effects you scroll affect your tone while you are doing it. Having two buttons with scroll up and scroll down would have been much better.
Looper is good enough.
