- Details of the coils:
Neck: 5300 turns (wound with a smaller bobin support and not magnetically backplate),
Middle: 5200 turns (reverse wound, reverse polarity),
Bridge: 5000 turns.
-
Specs of the coils:
Neck 7 KOhm - 1,6 H (not magnetically backplate)
Middle 7,3 KOhm - 2,3 H (RWRP)
Bridge 7,2 KOhm - 2,2 H
-
Details of the magnet (isotropic ferrite magnets):
Dimension of a single bar (every pickup needs two bars glued together):
length - 28/28,5/29 mm
width - 8 mm
height - 8 mm
Neck: North pole facing the strings, coil wound clockwise.
Middle: South pole facing the strings, coil wound reverse clockwise.
Bridge: North pole facing the strings, coil wound clockwise.
This magnets are out of production so you should find some company for custom production.
I purchase the magnets from www.algamagnet...

The temporary support must have the following dimensions:
length - 62 mm
width - 10,5 mm
height - 5,7 mm
Attention: width and height refer to the two blocks, the length refers to the distance between the left side of the left block and the right side of the right block.
The cardboard strip must be with height 5,8 or 5,9 mm.
For neck coil you need a smaller length temporary support to achieve right inductance (1,6 H) with lower resistance than bridge coil (7 KOhm).

Details about wire:
44 awg enamelled copper magnet wire with insulating Formvar.
With 250g of spool you should be able to wind about 10 or 11 coils.

To make a Mosrite pickup.
Follow the steps in this video, don't wrap the windings in tape but dip the coil in blue epoxy.
A friend of mine had to rewind the pickup in my Ventures bass, when he removed the pickup and dissembled it, there was a blue epoxy donut inside with the magnet in the center.
Nice!!
No, thank you for the video. I’ve been trying to unlock this puzzle for a while now. This helps a lot!
Thank you, let me know if you need help or you have some doubt.😀
The video is very useful, thank you! Could you tell me which pickups use magnetic baseplate and covers, and which ones don't. I got confused in the description of the video XD
I will be grateful for your reply!
Thank you so much! The pickups with magnetically baseplate are mid and bridge pickups. The one with not magnetically baseplate is the neck pickup.
Are the tri sonics higher than normal single coils?, I plan to place them just in top of the pickguard, otherwise i will need to file down the pickguard, i have a yamaha strat style guitar
Yes, they are larger and higher than standard single coils but not so large like p90 or humbucker. Adapting the pickguard is always the best solution for me.
Livio, thanks for the video and the information on the pickups!
You mention the temporary winding support for the neck pickup needs to be smaller than 62mm ... how much smaller?
Hey thank you! The neck coil should be much more tight to the 2 bars magnets than middle coil and bridge coil. The lenght of the two bars magnets glued together should be 57mm, my temporary support for neck pickup is about 58mm so it’s pretty tight and there’s no risk that coil could not fit into the whole structure.
Do your coils ever try curl up or twist when removed from the support? Im having this issue.
If you use epoxy resin (like Brian May did) you can't remove coils from support anymore, if you remove coil from baseplate you'll break it. If you are referring to removing the coil from the temporary support, after finishing winding you need to put the tape around the coil before, then you can remove the bobbin from the temporary support.
How did you extract the coil out of the coil former bracket? I see there's tape on the ends of the coil, how did you get it on there without the coil collapsing when you removed the end bracket? Every time I've ever attempted to wind an air coil (using the same configuration as yours, a temporary coil form with a cardboard strip core), the ends bust apart and the wire goes everywhere. The best solution I could come up with was to dip the coil and the coil former together in wax and remove the bracket after the wax set.
If you look at my temporary epoxy resin support shown in the video, you will notice that there are two small "channels" which are essential to be able to insert the adhesive tape to wrap around the coil when you have completed the wrapping, this allows you to have a considerable stability to then be able to dismantle the coil from the temporary support without the coil collapsing.
Great video. Do Tri-Sonics suffer from feedback and microphonic problems as they’re not potted? Thanks.
Thank you! Yes, standard Tri-Sonics from 60's were not wax potted to keep low cost production but they had problems of larsen and microphonic effect. Brian May fixed his Tri-Sonics with epoxy resin. Now all Tri-Sonics model from Burns are wax potted.
Livio Bellini - Thanks for the reply. Tri-Sonics have such a unique sound. If only I had a spare £400 hanging around, I’d get myself a Burns Marquee Bass.
@@revlewisrees9880 I prefer Burns Nu Sonic bass. :D
hello, could you tell me what is the voltage or electric current of the guitar pickup?
I think it’s about some uV (micro Volt) and electric current is near 0 Ampere.
@@absolutely_senna thank you
Are the pickup shields / base plates usually connected to the circuit ground ?
Yes, shields and baseplates must be connected to the ground of the circuit.
@@absolutely_sennathanks!
Would you normally do that with a third separate wire, so signal +/- wires can be independently flipped for phase etc?
@EvLoutonian Yes for sure, if you want the in phase/out of phase feature it’s necessary to manage the ground on a third separate wire. I use the cable with red wire, white wire and ground wire (wrapped around the red and white wire). This also helps Tri-Sonic to reduce the ground noise.
@@absolutely_sennaok, fantastic. Makes sense.
Thanks again for the reply.
I think my (60's Hofner) guitar has (perhaps original 60's) Tri-Sonic pickups installed.. (by previous owner somewhere along the line).
But there doesn't seem to be a separate shield / ground wire.
Just signal wires, with nothing attached to the pickup plate or cover, as far as I can tell.
Do you know if that would be normal for the r original design?
(Or perhaps these pickups are a more modern reproduction of some sort, I'm not really sure how to properly identify them, but I took some photos inside etc)
Might you know any other placed to purchase the covers? The supplier in the UK that you link too for the magnets is out of supply.
I’m sorry, I know only Axesrus.
@@absolutely_senna Thanks for info.
@@spidey4fun You better wait because I think the backplates and topcases will be back soon available, the problem is that there are a lot of import taxes when I buy from Axesrus because of the damn Brexit (I am from Italy).🤦🏻♂️
If you go on Axesrus site, baseplates for TriSonics are back available.💪🏻
@@absolutely_senna Excellent.
Great info I need some magnets just need now are they expensive?
I pay them from Algamagneti 60€ for 1 set (6x magnets). But I think that for big orders you will pay a lower price.
Thanks
@@akaski777 if you are still searching magnets, go here, they are selling them at a good price.😀👍🏻

Did u try them on an guitar if so how was the sound quality
Cuz i am trying to build my brian may style guitar thats why and this culd help me
@@depressed_neutron I'll do a video when I will finish construction of Treble Booster Touring.👍🏻😀
@@depressed_neutron if you want to hear the sound of these pickups, look this video, it's a cover of a Thin Lizzy's song. Both the guitars are equipped with my Tri-Sonics. The Natural RS has all 3 pickups on with neck out of phase.
The Antique Cherry RS has bridge and neck on with neck out of phase.
The signal chain is guitar -> Treble Booster Touring -> amp simulator in Logic Pro X.

Hello sir can you tell the specifications of the magnet each pickups the dimensions of it?
Each pickup needs 2 magnets glued together with the pole facing in the same direction (North+North or South+South). The type of magnet is ceramic isotropic ferrite called “C1” or “Y10T”. The measurement of every magnet is 28,5mm X 8mm X 8mm.
@@absolutely_senna thank you sir.
@@brianhm1966 you are welcome.
Purtroppo qui sono linkato col vecchio Nikname ma su Accordo con Black Almond ;) Grazie Ancora per il link che mi hai lasciato di la, veramente interessantissimo,.. ne faccio tesoro ;) poi ti diro' come va :)
Figurati!😃
Text too small to read.
Gee, I wonder why this method of pickup winding isn't more standard ..said captain sarcasm.
the tri-sonics want to live 4ver
Trust me, they will live forever..🙏🏻
something ins wrong here !!! the burns trisonic had that name for something, they had 3 wires output in every pickup !!!!! this wiring is wrong as far i can see !!!!
These pickups are called “trisonic” because they pick up the string at three different points: blade, magnet and second blade. However, it is still useful remembering what Adrian Turner said in an interview: the blades of the baseplate have little variation of the magnetic field, the point where there is the greatest variation of the magnetic field is the magnet itself. About the three output wires, they are:
start of bobin, end of bobin, ground.
