Sho bud push pull? Never heard of it. You mean Emmons push pull? Or sho bud pull release? Sho bud all pull?

| Google Patents will almost certainly have the patent drawings for your perusal. They're not dimensioned, but there's still a lot of info to be had by sleuthing them. |

It is the Emmons but was going to be the Sho Bud but Shot would not make the change that Buddy wanted to do. in 1961 |

https://patents.google.com/patent/US7465860B2.
This system is similar to what BMI has done, with two separate changers, as opposed to the nested PP changer system that Buddy and Ron Lashley devised (https://patents.google.com/patent/US3447413A).
If you type "David H Jackson" in the "inventor" field you'll get a whole bunch of other stuff. A lot of the patents weren't filed until fairly recently. I've spent hours before digging through psg history via the patents. It's pretty fascinating. Check out the citation links at the bottom, the various patent numbers cited in each filing. There are countless others examples of "prior art", just about everything that's been tried or imagined, some very obscure. Endless rabbit holes...

| Great post. If you click on Ronald Lashley you can see the patents for split tuning and the counterforce. Thanks for posting. |

| What I also find fascinating is the technical write-up that accompanied the drawings to describe each specific component - and its function. |

| I wonder if Lashley - a physics teacher - or a lawyer wrote it. Or combination of both. |
