This is the end of wandering around in the fog. Guitar synthesizers have a dedicated chapter, too. Strong eddy currents can also occur in metal covers; these currents vanish when the covers are removed.

Electric Guitar – Sound Secrets and Technology: : Helmuth Lemme: Books

Position and height of the peak vary from type to type. Write a customer review. If you are familiar with them, use this book to reach the next level. As the induced voltage in the pickup is proportional to the variation of the magnetic field with time, the driving current through the coil must be inversely proportional to the frequency.

The passive low-pass filter works as a voltage amplifier here but doesn’t amplify power because the output current becomes correspondingly low, as with a transformer. This induces a voltage by changing the magnetic flux through the coils.

Some comments The measured result is really precise only for single coil pickups. The arrangement of the magnets is different for different pickups.

John October 27, 3: Don’t get scared by the somewhat pricey tag. Electrical equivalent circuit of a magnetic pickup A real coil can be described electrically as an ideal inductance L lemem series with an Ohmic resistance R, and parallel to both a winding capacitance C. In practice, this is very difficult to do.

An unbelievable cult has developed around pickups, inflamed by advertising managers and music magazines. Thanks to the author for permission to share his article here with you. This will give you the possibility to adjust the resonant frequency and the resonance height continuously with potentiometers, instead of only in discrete steps.

With a few deft interventions, many instruments can be rendered more versatile and made to sound a lot better – in the most cost-effective manner. The Pickup as Circuit From an electrical standpoint, a magnetic guitar pickup is equivalent to the circuit in Fig.

Published in both German and English, it is plentiful of occasions to bring myths down. So you can imitate the sound characteristics of many different guitar and bass pickups. This slope is inversely proportional to the threefold power of the frequency. How Resonance Affects Sound The resonant frequency of helmut available pickups in combination with normal guitar cables lies between 2, and 5, Hz.

Many “pickup experts” have never heard the lemke “inductance”. Sample variations of the pickup series can be recognized quickly, deviants can be identified and sorted out.

The external load consists of resistance the volume and tone potentiometer in the guitar, and any resistance to ground at the amplifier input and capacitance due to the capacitance between the hot lead and shield in the guitar cable. My library Help Advanced Book Search. Most helpful customer reviews on Lemem. For the interested musician and othersthis book unveils, in a simple and well-grounded way, what have, until now, been regarded as manufacturer secrets.

In fact, the frequency response can be smooth and simple enough to be easily described with a mathematical formula. Amazon Second Chance Pass it on, trade it in, give it a second life.

With only a little expense for electronic components, the sound can be shaped within wide limits. But with too short a distance, the magnets pull the strings, and harmonics are shifted so that they are no longer exact multiples of the fundamental frequency, but a little higher or lower.

He has thoroughly tested everything described here, in practice. With the strings at rest, the magnetic flux through the coil s is constant. Craig October 27, It is connected via two audio cables to the sound card which works als digital to analog and analog to digital converter. In many cases these cores are screws, so level differences between strings can be evened out by screwing the core further in or out.

Share your thoughts with other customers. But the resistance is the least interesting magnitude of all. The absolute value is not important; what matters is the position of the resonance peak and its height above the overall amplitude at lower frequencies.

This book balances and integrates theoretical and practical topics, all accompanied with the corresponding references in the form of tables, wiring diagrams and charts. A few pickup manufacturers know that fact but they conceal it. Resonant frequencies of some well-know pickups for various parallel capacitors.

Some pickups have a metal cover for shielding and protection of the coils, others have a plastic cover that does not shield against electromagnetic interference, and still others have only isolating tape for pemme the wire.

There are so many pickups on the market that it is difficult to get a comprehensive overview. The new second version Fig. High overtones, where the peak of the waveform occurs over one pole and the trough valley of the wave occurs over the other, can produce cancellations.

Thirdly, they cause the frequency transmission curve to drop slightly below the resonant frequency, as shown in Fig.
