Hi Mark, Here's a question for ya.. I see that hijack has the ability to switch to the AUX source and back again when the cell phone mute line triggers. I was thinking of wiring up my CB radio to the AUX in and hacking the squelch control to trigger the cell phone mute line. However the squelch on/off can happen very rapidly and for any amount of time from milliseconds to minutes. Will the Empeg be able to switch that quickly to AUX and back again? Do you think the Empeg or hijack will get confused? Thanks, -Ryan.
