Title: Tone Control
Post by: serpenta on September 08, 2004, 10:13:07 PM
Can somebody explain to me how tone control works, i have this bleak idea of how it works by putting resistors and caps together in parallel but thats pretty much it.  Any help would be appreciated.

try this site (http://www.allaboutcircuits.com/vol_2/chpt_8/index.html)

Search google for things like "low pass filter" and "high pass filter" or "RC filter" (RC standing for resistor/capacitor)

Basically, the combination of a resistor and a capacitor forms a filter. Depending on which is placed where will determine if it's a high or a low pass filter. The values of the components affect the cutoff frequency of the filter (ie; the frequency at which the filter is set)

While you're reading, try to think of a capacitor as a device that will let AC pass through it  much more easily than DC. (In fact, in an ideal world, NO DC can pass through a capacitor)

A tone control is just an adjustable filter.
