[1][2] In a transformer, coil taps are often used on both the input and output coils, to compensate for differing supply potential and to provide a range of output potentials respectively.
Coil taps on inductors are quite rare, but are sometimes used for band switching in tuning circuits.
Coil pickups used with measuring instruments often feature coil taps to compensate for band rejection or equipment input impedance.
[citation needed] Single coil magnetic pickups found in electric guitars can be coil tapped to reduce the number of windings around the magnet.
The guitarist can then choose between the loud, punchy, midrange-heavy sound of the entire coil, or 'tap' into the inner coil for a quieter, yet bright vintage tone with a more clear and detailed high end.
