when you mix the sound try sending the guitar track to a bus with a compressor on it that does sidechaining. Adjust the sidechain high and low pass filters so it only compresses the picking sound, eg from 7khz-11khz, find the exact frequency where it sticks out too much, make the ratio around 4.1-8.1 so you can clearly hear the compression, fast release, fast attack, threshold set so it only just compresses the loudest parts BOOM,
the rest of the sound is unaffected by the compressor so it will sound very natural without ruining your tone, be carefull though not to take out too much or it will take out some important harmonics
