Hello, I hope that is the right place to ask.

Can someone tell me what frequencies an electricial Guitar puts out?

The highest Tone is the high E String @ Fret 24 at my Guitar. If it is tuning right, it must be a frequence around 1318,5Hz (Tone e''').

Now at an Schematic found at the Internet, the builder puts an 470pF Capacitor parallel (to the pulldown resistor) to ground at the Input before the Grid-Resistor. If I take the formula Fcuttoff=1/2PiRC at take the Outputimpedance of my Humbucker (~13k Ohms) I'll get ~24kHz. He told that je added an Tonecap, but does an Guitar really give those high frequencys?

I hope some like to help me.

Cheers

in reality you have harmonics on top of the fundamental tones,those can go over 10Khz,you don't hear much of them because guitar speakers have a major rolloff from 4/5 Khz,if you plug into a full range speaker you will hear a screeching sound.
That cap in parallel can be too much depending on the cable capacitance you use from the guitar and eventual pedals.
