Just wondering if anybody has replaced the power switch? I love the amps, and the mini power toggle seems cool until you try and take the amp out somewhere. Just about every time I take the unit somewhere the switch gets turned on accidently and I drain the batteries. I have both versions and was thinking about ripping the 5 apart and putting in a different style switch, and if that goes well, maybe doing it to both of them. I was thinking about a solid push-button, maybe a foot switch if it will fit. Has anybody here opened one up yet? Or even considered this mod?
