| Just checking up out there with all you Pickup wizards. Here's the question . a 12 string usually has a 18 to 21 K ohm reading .. what would happen to the tone if you lowered the windings to say 13.8 K ohms? would it get thinner and brighter? or just have no punch .. would it sound more like an old Sho Bud ? Let me know what you think .. |

| All other things being equal, the fewer windings, the thinner the sound. You would also have less output from the pickup. Can be a good thing...Jerry |

| My own experience with 12 string single coil pickups: I started with a TrueTone wound to about 20K. I later had it rewound to 18K and liked it a lot more. I also have another one which is 17K with a tap at 15.5K. It seems to me that 17-18K is the point at which you have all the brightness you are going to get and going lower they just get nasally thin. There seems to be a very slight difference between 17K and 18K and, to my ear at least, the 15.5K is almost unusably thin. I routinely use the 17K version. This is all just my own opinion of course but I think that just about everyone likes dealing with Jerry Wallace! |

Scott,
I rewound my broken Sho~Bud 12-string pickup (AWG42) and it reads 18,1K with a split tap at around 12K.
After I did that, I recieved an email reply from Jerry Wallace where he recommended about 19,5K for a 12-string Sho~Bud singlecoil.
I like the full coil sound a lot and the split sounds is quite thinner (not in a bad way) and has more edge to it- it´s another sound option that fits very well sometimes. Guess next time I might try 19K/ 15K, just to check that out. |

| I had Jerry Wallace wind me a 19.5K pickup for my U-12 Zum and never have wanted for anything else. It sounds very rich with silky highs and clear lows (no mud) I had been using a BL-912, but, could never get the sound I wanted. |

Pardon my ignorance, but when you wind the coil to a lower value, evidentally there is less wire. Do you use a thicker gauge to keep the total diameter similar, or does it matter? I just assume all wire has approx. the same resistance.
Thanks, Bill |

| Actually, thinner wire has a higher resistance but it is impedance and not resistance that is the issue at hand. As the impedance of a given transducer coil changes with frequency, coils with different impedance curves will have differing frequency responses, thus pickups of different impedance - even if they have identical DC resistance - will have notably different tonal characteristics. |
