Major Overdrive (announced 10-22-15)(How many made?)(Highest known number – )
Marc Says (via TGP)

“The Major Overdrive takes the HFD as its starting point and pares down the number of knobs and adds an extra pole to the tone control to address the HFD’s issue of being too bright for some amps. The overall tone is more focused and targeted more specifically to a huge Marshall plexi (or even a Marshall Major) sound since I had to have a particular tone in mind when fixing the response of the previously adjustable parameters.”

"...with my Major Overdrive, I went from a 47pf to a 470pf value on one of the filters in the negative-feedback of the fuzz section. This gives is a much more "brown" sound since the Major focuses more on the high-gain, chewy side of things."

The Major does have an extra filter stage compared to the Hybrid Fuzz Driver (but it is a very mild filter), as a few people found the HFD too bright, but that just gives the tone knob better range in the CCW zone, IMO, while still yielding abundant presence at max. Since its focused more on the high-gain and aggressive side, I did set its internal filter points a bit darker so it sounds more like an overdriven cranked amp rather than a raw fuzz when its distortion is fully engaged.

I hope I did not lead anyone to believe that the Major Overdrive is just a clone of the Hybrid Fuzz Driver. I used the Hybrid’s topology as my starting point, but what I did with the Major is something with a clearer, more dynamic, biting attack and a slightly rounder lower-midrange profile. How much fun would it be if I just made it sound the same? I mean, if you wanted an HFD, you’d buy an HFD.

The transistors I’m using have a little more of a full eq response compared to those used in the HFD, so there’s more “body,” but it’s a subtle difference. Where the HFD is more streamlined and compressed, the Major has a touch more punch and dynamics. My analogy is if it was like an amp, it would be one with a huge output transformer that kicks harder and is less-easily saturated.

“Just speaking for myself, I made the Skreddy Major Overdrive really in an effort to focus specifically on EVH’s tone, which was pretty much always just slightly goosed by his EP3 and perhaps softened somewhat by his variac feeding it a lower voltage than the typical wall socket would supply. The cranked plexi tone is known as a firebreather (AC/DC, et al), but really I think it is better represented by Hendrix at Monterey and Page at Madison Square Garden (which I know he probably used more than just a stock Super Lead and probably it was a Major 200W version, but really the sound is quite nearly identical just louder), then Page looks like he may have been using a Uni-Drive as a booster for the fuzzier parts.”
