Thanks for another great video! I've never had much luck with L and C values from manufacturers. I test pickups myself with a low z driver coil, sig gen and scope, to find their resonant frequncy. Then I work backwards with formulas or spice to work out the actual inductance and parasitic capacitance. You have to remember to account for the input capacitance of your scope, though.

[@erikvincent5846]

Yep. Especially when you are dealing in the picofarad range, scope input capacitance is "a thing"

[@peterjohnson4932]

@Rob Mods. That sounds great! How about making a video explaining/ demonstrating it all? Out of curiosity I looked to see if you made vids and you do. Watched a couple and subbed!

[@roadtonever]

I like to use simulations like this to chose a tone cap value that gives me a bump around 2.5kHz. Its pretty cool on a low output single coil guitar because go can go from a Fenderey clean sound to a thick Gibsoney at the turn of a knob.

Stock Passive Alnico 5 Humbuckers in my PRS SE 245 Custom. If you get the right height they sound amazing. Greetings from Italy :)

Hi any chance you would do a klon style kit/pcb soon? Cheers

[@vredzhepov]

Are there any videos related to measuring the frequency response of your devices?

[@erikvincent5846]

We do. Any particular one you are looking at? If we don't have it, it shouldn't be hard to make up a video on that.

Would the pots be A/log or B/lin? Supplementary; is a D reverse B? Just wondering.

[@erikvincent5846]

Hi Steve, good question. The pots on most of my guitars are A/Log. However, my Glarry Bass originally had B/Lin for both the volume and tone. I have since upgraded the pots to CTS A/Log ones. I've only seen A/Log, B/Lin, and C/Reverse Log, so I don't believe I've ever ran into a D. And let the jokes fly on that statement.

[@itchyviking]

Thanks for answering. Linear logically sounds more likely. I've put together a couple of chorus pedal circuits and Bs seem to give more range.

@@erikvincent5846 Would you be willing to run a private simulation for my Tele?

[@gourabshow3993]

👍

[@DavidRavenMoon]

You’re showing your humbucker wired in parallel. It should be series. In parallel it will be 3.95k To answer your last question( I’m a pickup maker, so I use my own pickups. They are passive. My bridge humbucker is similar to what you modeled.

[@erikvincent5846]

I thought in-series was wiring the output of the first "coil" into the input of the other "coil" which adds the outputs together?

[@DavidRavenMoon]

@@erikvincent5846 Yes, and now that I look again they are series. It was the virtual capacitor that threw me. 😄
