Is regulated or not, but if it isn't the current will drop off slightly as the battery starts to Of the 9v battery that provides current to the bridge. The differences could be the calibration, internal translation error and perhaps the state That is translated through a A/D converter chip/display chip to get digital readout. Through ohms law and a mathematicalįormula, the 3 known resistors (part of the ohms range you select) and the currentįlowing from the battery through all 4 resistances calculates the unknown "resistor" and Where X the unknown resistor is part of one leg of the the "diamond" of 3 known resistors The basic ohmeter is basically a measuring wheatstone bridge with a battery (9V usually). Not all inexpensive ohmeters are calibrated to exact National Standards. So it's a bit weird differences almost amount to 1K. Gibson have been able to wind to 0.25K tolerances since the early sixties. That's pretty much nailing Epiphone specs. My 57CH neck PU measures 7.8 K and the HOTCH bridge PU measures 14K ohms. Just wondering about the discrepancies between the pickup's resistance? If they have, you may want to try to gently tap them back down (with a sledgehammer - just kidding, I HOPE no one took that seriously) or you may need to check truss rod adjustment, or string action height. You will want to check the problem frets to make sure they have not come loose or lifted. Good metal-to-metal contact (Bad fret buzz) will have lower resistance - touch the 2 leads together just for fun, you'll see almost zero ohms resistance. The higher the reading, the less the string is touching the fret. The actual reading you get with the multimeter is not really that important other than the fact that it will give you a rough idea of the severity of the string and fret contact. Don’t be surprised to find multiple frets on one string giving you readings. This happens because the metal of the fret completes a resistance circuit with the metal of the string.ĥ. When you get a reading on the multimeter, you have found a fret that is coming in contact with the string. As the string is vibrating, touch each fret with the other multimeter lead probe. Mine is a 2.99 harbor freight special!) Using your right hand, pluck the string. Put the multimeter on the highest resistance setting (if this doesn't work for you, lower the setting, you may have a really crappy multimeter. You can also attach it to the string between the saddle and the tailpiece on guitars with tune-o-matic or similar bridges.Ĥ. Put an alligator clip on one of the multimeter probes and attach it to the string between the nut and the machine head. If the buzzing sound occurs when you strike the note on the fourth fret, then you will want to put the capo behind the fourth fret.ģ. Put the capo on the fret of the note you find the buzzing on. (You can eventually do this same process on every string if you WANT to.)Ģ. Starting at the first fret of the first string you will want to pick each note down the fretboard until you hear the "buzzing sound". Sit in your normal playing position, that way gravity won't pull headstockġ. Also, a capo is handy for holding the strings down in the position where you're getting the buzz. You want to have a pair of test leads with a clip built into the end. You need to have a digital or analog multimeter so that you can measure resistance. Will change a bit with temperature, but will be "close enough for government work". Move 3-way to "rhythm", repeat process to get neck reading. READ METER! You now have resistance value for bridge On the barrel (the roundy-looking thing) located ABOVE the plastic spacer ringīetween tip and barrel. Place one meter lead on TIP(the pointy thing), place other lead How amazing, the wonders of technology! TakeĪ multi-meter set to read resistance range as high as 15k+, select "treble" onģ-way switch. On the otherĮnd of the cord, you'll see a plug that looks exactly like the one you just Turn both B and N volumes up to 10 (11 in some folk's case!). Plug a standard gitar cord/cable into your axe, If you have LP Standard, yours will be same as per 2008 EPI catalog I have. Neck pickups are Alnico Classic Humbuckers

The above-listed Bridge pickups are Alnico Classic Plus Humbuckers, Just did a quick resistance reading the "easy way" (I'll explain) on both myĮPI LP Classic and EPI LP Studio, results as follows: YEP, and I'm sitting here with my multi-meter in hand, waiting for the
