cheers

Not that I'm by any means an 'expert' or 'authority' on these matters, but my desire for an old-school "just breaking up" tone led me down many paths. I've gone the sansamp route, fuzz, distortion, overdrive, and just about everything in between! One constant has emerged in my journey- real tube pre od pedals have the most natural low-gain breakup available. Of course, IME, but I've never found a transistor-based overdrive circuit that managed to have a great low-gain texture
and sound "old-timey"...
Not that transistors cannot do low-gain. The inexpensive Bogdan Polish Love pedal, for instance, has a great lightly overdriven capability - but it's lack of flexibility makes it sound too hi-fi. SansAmp technology is also revered for it's tube-emulation, but I have to admit that I'm no believer in their offerings as a stand-alone dirt pedal. Plus, "fat" isn't the usual term used to describe a SansAmp...
For what you're describing, I think that an EBS Valve Drive would be perfect. Older Tube Works pedals, a Mesa V-Twin or BottleRocket, or perhaps a Dave Hall tube preamp pedal would all be good choices. There's just something about a properly designed tube od that always feels more natural and organic to me.
To exactly "nail" the Jamerson tone is
far more about technique than gear, but getting a little dit and rolling off some highs does help!
