#4 - Pushrod moved over to "runoff slot", pull not engaged:
The spring screwed to the bellcrank and hooked over the pushrod holds it in either the "drive hole" or the "runoff slot", and allows for a quick switch. |

| Disclaimer - I scanned and posted these for Paul, but have absolutely no idea what this thing is or what it does. It's WAY over my head. |

| Well, from looking at it, I'd say the "accelerator" is just a type of slave lever permitting extra (more) movement of the 3rd string lower finger. No doubt he's dropping the 3rd a tone or more, and stock pulling train geometry won't cut it. There's no big "mystery", it's exactly the same as having a longer puller on the cross shaft. The exact same thing can also be accomplished with another (free-running) puller, so as to not have to use custom-fabricated parts. The so called "runoff slot" merely allows that 3rd string pull to be de-activated (when desired) without using any tools. |

| that is for is 3rd string whole tone drop from g#->f#. we like the effect of releasing the lowered 3rd string vs the whole tone raise on the 1st string [This message was edited by ebb on 02 September 2006 at 05:11 AM.] |

Donny - You nailed it 100%!! A couple of the captions don't match the pics, but they're pretty self-explanatory anyhow. The "runoff slot" is merely to save the .011" string so I'm not bending it needlessly all night long when I don't want the change.

Paul, how is the pull deactivated?, what makes it go to the runoff.

My left thumb and index finger!! The spring has minimal tension and acts strictly as a detent to keep the rod from falling out. I just reach under the guitar and move the rod from one to the other. I suppose I could have made some sophisticated shift mechanism, but it really wasn't necessary. It works very well as I found out last Saturday in Lostant IL. Sneaky would be proud!!
