Sho Bud Permanent Tuning Process

Post by Benjamin Franz »

Hey all, I’m curious to know if anyone can talk through the process of tuning a Permanent. Particularly the balance between the F# on the C Pedal and the D# on the E lower. Thanks in advance!

Do you have a secondary mechanism underneath to adjust those balanced notes? You need enough slack on the rod to let it raise and lower the string enough. Here is a thread with lots of info.

Over the years, the mechanisms Sho-Bud used for achieving a raise and lower on one string evolved. With that said, it would help to see a picture of the undercarriage of your guitar.

In my opinion, the best place for the Eb lever on a pull release is on LKR. Putting it on RKL requires a reversing mechanism and a whole lot more hardware, which can lead to more ways for the string not to return perfectly to pitch. The way my Marlens are setup, I don’t have to worry about leaving slack on the raise. It’s very simple, and returns to pitch perfectly.

For tuning the changes…
Hold the C pedal down, tune the F# note at the keyhead.
Let off the pedal, tune the open note by the length of the lower release rod. Its resting place, which is spring loaded, is what gives you the E note.
Engage the knee lever, and tune the Eb note with the final lower screw at the end of the changer. If that’s not working there’s some setup stuff that needs to be addressed.

Tiny adjustments here or there can make all the difference. I’d recommend spending a lot of time with the guitar upside down, watching what happens when you press and release pedals and knee levers.
