We got our hands on Neal Schon's old Mesa IIC+ long head fully loaded all options. We also got our hands on Flemming Rasmussen's Master of Puppets and ...And Justice for All... notes which includes Hetfield's IIC+ settings so Mark Cameron and I could dial in the best tones possible for this C+.
We also included boosted profiles with one of Mark's prototype pedals to mimic what the studio parametric EQ in the Metallica studio was doing.
Hands down we think this is the best IIC+ profile pack out there and with all the profiles included you will have plenty of options to dial in the tones you need.
We even used a stock white 1984 Gibson explorer with dirty finger pickups exactly like what Hetfield used back then. The guitar is white and all original, not a reissue or refinish.
