I've had three different BOSS pedals that I have difficulty reliably switching them on/off with the foot pedal. I'm assuming the internal microswitch is simply wearing out. Though I'm shocked that I've had this happen on three different boxes (out of the 5 I believe I've owned). The worst was an OC-2 which I'd probably have to stomp on like 5 times to get it to switch. My Metal Zone isn't as bad, but still takes a couple stomps usually. My LS-2 which is nearly brand new, though I bought it used, does it less often. While I'm thinking it's the pedals due to the fact three of them are doing this I'm thinking it might be user error. I'm assuming I should be able to simply stomp the damn thing (quick, slow, hard, light, shouldn't matter) and it should reliably turn on/off. Correct? I haven't had this problem on any other pedal by any other manufacturer, including others with soft switches like DOD. Related, does anyone have a cheap source for replacment micro switches assuming that's my problem? Thought I'd ask while I was already blathering away.
