That's just crazy talk. Who ever says something like this or believes this kind of gibberish has obviously never heard the following plectrum pioneers.
No, tone doesn't just magically "come from your fingers". That's crazy. Crazy talk I say! Sure it starts there but "tone" is a combination of many things. The instrument, the amp, the effects and maybe even a pick. At the end of the day all of these things are simply tools used to get whatever sound inside of your head and heart out to the ears of the listener.
Tell me who I missed. I'm sure that there are tones of great players who use a pick that I should check out. Let me know who they are in the comments below.
