    Trying to figure out input impedance, and how it affects coupling cap value choice

    I've gotten around to figuring out how to do some spice stuff as some of ye have suggested and yeah, it would appear that the pulldown resistor does indeed have an effect on input impedance. It acts in parallel to the resistor across the 4.5v supply on many circuits. Stupid question - does it...

    Trying to figure out input impedance, and how it affects coupling cap value choice

    Checked it out and while it is helpful for understanding impedance when it relates to interconnecting pieces of equipment in a variety of professional and non professional applications, it unfortunately it doesn't contain the information I'm looking for. I think the best way to describe what it...

    Trying to figure out input impedance, and how it affects coupling cap value choice

    Hello! I've been trying on and off over the past year or so to really try and nail this concept down and it has kind of driven me insane 😂 I'm looking for reliable information regarding how you should calculate the input impedance of a guitar pedal circuit and more specifically, whether or not...

    Why don't PedalPCB build docs tell you what trimmers are for?

    That makes sense to me. Nope, nothing specific I'm looking for (at the moment anyways haha) just was curious if I was missing anything obvious. Thanks for the quick response! I know that if for whatever reason I do get stuck I can always come to the community here for help.

    Why don't PedalPCB build docs tell you what trimmers are for?

    This may be a very silly question, but is there a reason that PedalPCB build docs don't contain any information on stuff like what trim pots are used for? What you're supposed to be measuring for and all that? Aion FX build docs always go into plenty detail in regards to this and even the...
