Hello,
Pete made these tones with a beta of FW10.
It turned out that the amps he used had not been MIMIC'd yet, so once that was done, the tone matches in his presets need to be re-done.
He's in the middle of the touring season now, so this will have to wait, but he said he will send them over.
If the artist using the presets he shared hasn't updated from the firmware he created them with, why should you if you want to use his presets?
For me, the benefits of upgraded firmware usually outweigh the usefullness of a collection of presets. I usually move on with the firmware.
