You can search custome tone for either Keith or the name of the song you are looking to ewmulate.

If your looking for that Phat bottom sound there is one out there called Keith Richards 2 that reuires minimal tweaking.

Using my pod hd 500 start a new preset. or use 13A of the podhd preset for vairax. that is in the last update of firmware.

Add Distoration BUZZ SAW to the effects chain. Add the pre amp BF Doubble with no cab.

Set the amp to  volume of 40%

treble 40%

Mid 40%

bass 55%

add reverb to the chain after the mixer and pre amp

use the vairax guitar models of Sepcial for the firebird v for songs like Can't get no

use the vairax guitar models spank for songs like Thumble the Dice.
