It is for this reason that many consider ceramic magnets to have a brittle sound, not their gauss strength. This has the effect of decreasing the inductance of the pickup and significantly raising the resonant frequency. The magnets at the lower end of the scale tend to produce a softer attack and a degree of “bloom” to the envelope of the note.Ĭeramic magnets should be considered as an individual case because they do not contain any nickel or iron. As the gauss strength goes up, so does the output. From there in order of ascending strength you have A2, A4, A5, A6, Ceramic and A8. Of the magnets we use, Alnico 3 has the lowest gauss strength.
In the case of pickups, the most significant characteristic is the gauss strength, which is a measure of the density of the magnetic field.
Magnet – We use several different magnet formulations: Alnico 2, Alnico 3, Alnico 4, Alnico 5, Alnico 6, Alnico 8 and Ceramic 5/8. DCR is often used as a gauge of output because as the turns increase, so does the output, though magnet type and the coil geometry also influence output. The length of the coil form, the number of turns and the gauge of wire all affect the DCR reading. DCR – Short for DC Resistance, is measured in Ohms and is the total resistance of the copper wire wound around a coil form.
