I don't think that anybody except EMG really knows for sure. There is no way that I know of to disassemble one without destroying it.
Please what is basic design of EMG pickups (Humbucker). I mean how look like from inside. Does it have pole or winding directly around the magnet. Well i have several preamp circuit for these type of pickup.
Please share here details about emg pickup.
2)Number of wire(awg)
4)Type of magnets
OK... a while back someone was kind enough to send me this:
He dissected an EMG 81
The coils are attached to the preamp in parallel, with the series connection to ground, and the other two ends to the (+) and (-) of the op amp.Magnet: Ceramic 56x3x13mm
Wire: 0,06mm (PE)
Core: 54x3x12,5mm (silicon steel?), solid steel.
Coil: 4,18KOhm (one coil), wax potted, aprox. 5500-6000 turns, h=7,5mm
Bobbin: 64x13x9mm (or with "tube legs" 12,2mm)
As a bonus here's also an EMG SA that I dissected.
What kind sound does an emg pickup have. Undistorted high Gain something ?
For this opamp preamp circuit must be used instead of transistor amp. I think
this can be used.
And thanks for the info
They sound like pickups. They run the two coils in a differential fashion to the op amp for low noise. Since the coils are buffered, they "tone model" the coils, probably by loading them to get a more passive tone.
They also have the entire pickup in a brass mesh Faraday cage.. at least the SA I took apart did. They are very quiet pickups. I like them quite a bit on guitar.
I got tired of them for bass.
I really only opened the SA because I'm nosey, and I'm not interested in copying one at all. I think their preamps are the key to their tone.
So is the EMG SA wired the same as the EMG 81 only with the coils stacked on each other with the magnet underneath?
Thanks for the helpful comment.
I don't have much experience with EMGs so it is interesting.
Would the SV, SAV and SLV have 2 coils in them like the SA although they call them active single coil pickups?
