Excellent piece of gear
I have used the ProCo Panic Button for switching my mic from front of house to my teams in-ears for years, but there was always a surge during the switch. Fortunately the surge always happened in the ears, not to FOH. I bought another PB for another worship leader, and this time the surge was a very noticeable pop to FOH. Called ProCo, and they basically said a 10dB attenuator was the fix. I got frustrated, and began looking, and found this. A bit pricey, but it has functioned perfectly, with silent switching and very solid construction. I like the different color LEDs beneath each channel. I'm very impressed, and will be replacing my other PB this coming year.
