Just got this in today to. Sound incredible. This is an early Mark III serial 152XX with a 105 transformer DRG.
Not quite as organic as the C+ but as close as you can get.
Nice!!! I got a III+ DRG that used to be a purple. I'm not sure what tranny is in it though. I haven't even looked. It definitely blows away my green stripe for sure. Congrats man!!! 8)
