Hi all, my first post.
I have built 3-strign and 4 string CBG and I am beyond hooked.
So my question is about pickups. How important is it to use a match string to pole. My first CBG was with an old 6-poll humbuker and it seems work just fine. But now that I have to buy some pickups I have a chance to be more specific.
And an extension to that question is what about the lipstick style. Those don't appear to specify polls.
BTW I have little technical knowledge about pickups, incase that is not already obvious.
And as long as you reading this if you have recommendation of pickups I would appreciate. I want to keep thing as inexpensive as possible but I don't want to buy crap.
The Firebird has the magnets as the rails, so you have to carefully remove the rails and press in the magnets without breaking the bobbins. The magnets don't need to protrude from beneath the assembly(the rails protruded to accommodate the magnet slung underneath) , the bottom needs to be flat for the bottom metal plate, then Maple spacers and then the base mounting plate as the original Firebirds were made as shown in the link I provided.
Some of the boutique winders that make Firebird pickups will omit the metal spacer and Maple spacers and just mount to the base mounting plate. I don't know if it will really make a big difference in the output tone or not to omit those pieces, but I'm going to use them in mine just in case it changes the Eddy Currents enough.
Some more infos about the Snake Oil Humbucker: underneath the pickup there is a ceramic magnet, the rails taken out of the pickup dont show any sign of magnetization, the cover is chrome over brass. cbgitty sells a pair of them for $26.99, I think a good deal for some first cbgs.
I agree that the Snake oil pickups are good. I compared them to the pickups I bought, the Snake OIl pickups are just a bit longer.
Did you measure the kOhms of the bobbins? They seem a lot slimmer than the Snake Oil ones with about ten kOhms both.
Viewed from top the Snake Oil bobbins are 12mm each, for 3mm blades.
I've never seen how a lipstick pickup is made. As far as strings over poles go. People angle the pickups so the strings go over the poles. But those who are builders can say more on how important it is.
If your looking for good quality try Fender pickups. You can get them through ebay for 100 to 120 a new set. Used for a lot cheaper. Up to $40 a pickup for original new Fenders. Buy a set of three and you have one pickup for three guitars.
i offer a simplified answer .
lining the poles up to the 3 strings on a cbg really does not make too much of a difference in sound .. the mag field radiates outwards , strings will still be picked up even in-between the poles . and 3 strings usually ride within the mid hot spot of a 6 pole pup anyway .
Some folks figure the slanted pup looks better and aligns them better, , and seems to match more visually . or may sound better closer over the poles . (another reason for the slanted pup is trying to get deeper tones on one side , and brighter on the other . (ie: closer to the neck will give a deeper tone .. for bass side closer to the bridge will be brighter on treble side .) or vise versa.
ps .. you can also hide the pickup inside under the lid .. if it's thin wood .. it will radiate right through the lid and still work . this saves artwork and vintage boxes too.
but .. either way i would still also recommend a covered pup , or a no pole humbucker.
Fender Bass guitars have the strings run between the poles without balance issues, but then those bass strings vibrate a lot more than regular guitar strings.
You still have a magnetic field that will detect vibration and send it to the coil along with body/neck/hardware vibrations even if the string isn't directly over the pole. I've always heard talk about string balance/unbalance and string fallout while bending the strings, but I've never experienced either while playing or noticed a significant change related to these issues. Yet;)
