Hello again. Over a month ago, I posted here for help in finding a fuzz pedal that could cop the fuzz bass tone on "Mean Mr. Mustard". After spending a fair amount of money on different pedals, I ultimately decided that one I already had—the DOD FX52—was the closest match. In that process, I came across a video that features the isolated bass for the entire ‘Abbey Road’ medley (presumably from the Beatles Rock Band stems). It's absolutely glorious. It's also revealing in how dirty the tone is, even on the stuff I had always thought was immaculately clean. I would guess it's the natural tube overdrive of either McCartney's amp or the EMI recording console. That is to say it's very touch sensitive-sounding. And nowhere is this more prominent than on "Sun King", where the bass goes from slightly gritty to really overdriven (but not quite fuzz) when the chorus kicks in. "You Never Give Me Your Money" also has a nice bite to it. So that's the kind of thing I'm looking for in an overdrive pedal: touch sensitivity that, with the pedal engaged, can go from my normal tone to an overdriven sound depending on how hard I dig in. I've seen a ton of threads on this, where the Catalinbread SFT and Fairfield Barbershop are both recommended. But I also saw good things about the Pigtronix Fat Drive and Pigtronix Bass Fat Drive, not to mention the Ibanez Bass Tube Screaner. Those three are all considerably cheaper so I'm wondering if anyone can attest to their touch sensitivity as compared to the isolated bass in the ‘Abbey Road’ medley. And can anyone speak to the differences between the Fat Drive and the Bass Fat Drive? It seems like people liked the original Fat Drive just fine for bass. It can be purchased for much cheaper than the Bass Fat Drive, so I'm just curious. Things to consider if you're going to recommend a different pedal altogether: I'm trying to spend less than $100 and I'm not interested in messing around with any funky adaptors / high current draw (i.e. English Muff'n). As always, I'm in debt to you all! Thanks. P.S. I'm not in a Beatles tribute band—I'm just a freak.
