The blue stripes come with no capacitor at C30. It's one of the reasons the blue stripes are the most aggressive.
The red stripes come with, IIRC a 500 pf cap there. That's from what I understand a main difference between blue & red.
Mike B. likes to mod them with a 1000 pf cap to smooth out the lead channel. He told me if I didn't like it that I could just snip it out and it'll be like it was. He also told me that he recommends leaving it in, and just turn the knobs to find the sound I'm looking for.
The clip I posted a couple posts back was the DRG amp with the 1000 pf cap in C30. If I had it to do over again I might ask him to put a 500 pf there. Or, I still may snip it out some day.
This clip is a different blue stripe DG I had that was all stock. same camera, same basic settings. Both Mesa V30s but 1x12 vs. 4x12. Notice how it is more harsh, and more aggressive. In a way I like it more for how forward it is but when you turn it up it does get a bit more harsh on the ears. https://youtu.be/kgM6VrHnnK4
