changing first string RKL raise from G to G# on p/p

Hamilton Belk · Post by **Hamilton Belk** » 14 Mar 2022 10:05 am

I'd like to change my push/pull SD10 so that the RKL raises string 1 to G#. It currently raises to string 1 G and lowers string 6 to G. I've never worked on the undercarriage before. Can anyone steer me in the right direction?

The G# raise on 1 is a long pull, you'll want to have the raise hook in the hole closest to the changer axle. You can also use a Sho-Bud 2-hole bell crank and swivel for a little better leverage to shorten the pull a bit. If you're handy it's best to drill and tap a new 8-32 set screw hole in the Sho-Bud crank, they're in a different position than the flat on the Emmons cross shaft.

If I remember right, I had to lengthen the bellcrank in order to make that change.

Since that string doesn’t lower, you can use the lowering rod hole for your raise hook. On that string only, you’ll use the lowering screw to tune the F# ( the G# tunes where it contacts the body. See pics.

F#

G#
I have that change on both of my PPs, and it works well.

For whatever it's worth, I raise String 1 F# > G# with a standard bellcrank using the changer pull rod hole closest to the top of the changer, as mentioned above. No difficulties on my '70's ST-12.

It can be a little tricky getting the hook into that hole until you get the hang of it. Note that the changer finger is thicker at that hole so where the hook comes through and sticks out on the top hole, it will not stick out on that bottom hole. I kept thinking that it wasn't in. I was wrong.

Dave, I got the change but only with my lowering screw sticking out quite a bit, which makes me think I did something wrong..

You need to remove the open tuning screw from the lower finger.

I agree with Jon, you should not need to use the lowering finger work-around to get a satisfactory whole step pull on 1. If you do go that route you need to make sure the neutral tuning screw is cranked in far enough that it doesn't hit the inside of the end plate when you release the pull. And yes, you might need a shorter lower tuning screw, as it is no longer operating in the range it was originally designed for.

Remove the screw that tunes the 'natural' note completely (bottom row). That lets the raise finger rest against the back of the basket (see photo). Then, you'll use the screw that would normally tune the lower (upper row) to tune the 'natural' note.
Shoot me an email if you have any problems, and we can do a video call.

Why not simply leave it as is, and grab the first string with your little finger behind the bar in conjunction with the knee lever to pull the string up to G#? Works for me on my push/pulls.

I guess having it on the lever seems like it would be easier to play for me. I like the idea though.

What Dave Meis said. I've set up dozens of P/P this way. It seemed to be the best way to do it.

Yes, I agree, best way to raise 1st string. It can be done normal way a string is raised but makes a longer throw on knee lever. This way, pull length is normal.
