    Finally I know why I get lower results when you measure from outside!!! Great to know how to correct those values too!!!

    So awesome. I always wondered how accurate the others were by using so many other factors tied into the reading. You have settled it! HhahHa. Great!

      Pretty easy and accurate. You can get quick and accurate readings from outside the guitar if you know what you are doing! I hope the vid shades some light to people who are not into the electronic part of life lol!

    I measured my pickup from the outside, and the multimeter doesn't give a reading (it just says 1.). What does that mean?

    • @LostPlectrum
      @LostPlectrum  3 ปีที่แล้ว +1

      Hi there, did you set it properly for resistance measurements? Set it to 20k? Volume pot full up at 10? What guitar is that?

      @@LostPlectrum hi, thank you for replying. Yes, I had set everything properly ( 20k ohms, max volume, etc...). I'd like l to add that there's no sound coming from my guitar either. Does that mean that I have to change my pickups? Could the problem be something else, like the switch, or something? Thank you in advance.

    • @LostPlectrum
      @LostPlectrum  3 ปีที่แล้ว +1

      Ok, you have an open circuit then. Could be a dead pickup (broken wire for instance), or a cold soldering somewhere that eventually detached. Time to open the guitar and check!

    Greetings Alberto Guitar Lover. Unfortunately I do not write or read the English language, even worse I understand it. Right now I am using a translator program. The information you provide in this video is of great interest to me. I have a fender stratocaster. In summary, when measuring the resistance of the pickup using the "short wire" method, what is the margin of error compared to if the measurement were made directly from the terminals of the pickup without being connected to anything?. I understand that using this method the result is less than the real value. Greetings.

    • @LostPlectrum
      @LostPlectrum  3 ปีที่แล้ว

      Hello and thank you. If you are measuring from outside the guitar, with a jack cable connected to the guitar, you have an error due to the volume pot resistance (on strats and teles at least). You can use the formula shown at 9.24 mark to calculate the proper value of the pickup. The difference is not very high as you can see, and that's due to the fact that the Volume pot resistance (250k) is far higher than the pickup resistance (around 6k in this case). This huge difference is limiting the error on the reading. I hope this helps!

    Hi! Do these formulas work on guitars like jazz masters where there are two circuits that a pickup passes through?

    • @LostPlectrum
      @LostPlectrum  2 ปีที่แล้ว +1

      Good question, I have little knowledge on jazzmasters, however if the pickups pass through two circuits I suspect you need different formulas.
