Re: op amp-based effects loop circuit for guitar amplifier

Hello Eric,

I am trying to avoid electrolytic caps in the signal path your point
about safety is valid.


Take film caps. Worth the few extra pennies.

Out of curiousity, is it common for op amps to leak DC when they fail?

They contain output transistors on the chip. One to the positive and one to the negative rail. If one decides to short out then yes, they can dump a whole lot of current into whatever is connected. Or whatever the current limit on the power rail provides.
