  • JB and Distortion - winds

    Hi! Do Jb and Distortion has the same winds/coils or different?
    I bought Duncan JB without sticker and I think it id Distortion or moded JB, because has double thick ceramic magnet. If I share photos, you can identify it?

    Not need to. The presence of ceramic magnets indicate a Duncan Distortion.

    And no, the DD and JB winds are not the same, although they're so close that only your dog might hear the difference, once you change the present magnets with a single A5.

      I bought this pickup on second hand, so I want to know how model it is for sure. Do jb and dd have any characteristic features?

        JB will say SH4 or TB4. Distortion will say SH6 or TB6. The magnet of the Distortion is thick, I'd guess 5mm versus 2.5 of the regular magnet (ballpark estimate).

            Correct. There's no such thing as 2 pickups which are the same but somehow have some completely different characteristics.

              After making the swap, it was by no means apparent to me at all, so if I have to put a finger on it, I blame the way the rig the guitar was put through was setup.

              That's all I can say, as the tone the guy chose to play, which for me was like a swarm of very angry wasps, didn't really make it easy to test.

              All I know is, he liked what he heard after the swap, I got paid, so it was a win/win situation for me, specially being kinda opposite of my average kind of customer, and I couldn't get out fast enough... gett off my lawn, kids!!! Man, I'm ooooooold...!!!

                Actually, I locked the other thread because I tried to get it back to your question, and I was ignored.
                My thought about this topic is
                1. I don't now the answer
                2. I don't care

                Both are pickups I would literally never use. But I get that people without any knowledge might have fun speculating. Hopefully the end result is better music made in the end.

                  Using inductance it's quite easy to spot the difference. Inductance is not on most peoples multimeters. The multimeter I recommend for people without spending 100s of dollars is a Mastech MS8269 or similar. You can get one on amazon for around 20-40$ American.

                  As most know DC resistance can go up or down depending on the temperature of the area you test in. H as in Henries is our unit. Megahenries are not as strong. I did a post yesterday comparing megahenries to megabytes versus Henries that are like gigabytes. Both are actual measurements. Round them to a solid number. I have a ton of name brand pickups measured like this and written down for those interested. The difference of 1 Henry of inductance is a much bigger than 1k of resistance. The usual range is 3-10H on average for passive humbuckers.

                  both of these were pickups I had in builds.

                  SH-4 - JB
                  15.98 k DC resistance
                  8.58H Inductance

                  SH-6 - Distortion
                  16.58k - DC resistance
                  7.5H - inductance

                  this is the multimeter I recommend for those who don't have one and again don't want to spend 100s of dollars. In real world situations there is a few other uses a guitar tech could use for this such as measuring capacitors that the letters are gone off them and testing wiring using inductance reassures us if a pickup is series out of phase.

                    DC Resistance:
                    Series: 17,67k
                    Parallel: 4,42k
                    North coil: 8,84k
                    South coil:8,87k
                    I done a few photos this pickup. I raised cloth cover and except double thick ceramic magnet, has two double thick plastic spacers.

                      They sound completely different, their unique winds cause the JB to be 1 Henry hotter but they're the same. LOL

                        Great! Now change the magnet on the DD and put a single A5, THEN measure the inductance again. My take is, that 1 Henry difference will disappear and read just about the stock JB.

                        Well...?

                          ^ Putting a weaker mag in the DD would cause its inductance to go up?

                            Yes. It’s the metallurgy.

                              So the output would go down while the inductance would go up? I thought inductance was an accurate representation of output?
