Tremolo arm touches volume poti (JP Dragon Blood)

[Fabio]

Hello,

I am from Austria and new to the forum so excuse my english please . I recently bought a Ernie Ball John Petrucci 7 string from 2020. As I researched in the internet the set up of the guitar is as it should be (Bridge is on the same level as the body and parallel to it) but in contrast to videos of John playing his JP models, my tremolo arm always hits the volume poti when I try to shove it out of my hands way. Is there a way to adjust the height of the trem arm in the trem cavity? I attached a picture of the trem arm because maybe it is not the original one. Thanks for your answers in advance.

Cheers,
Fabio

The trem bar doesn’t look right to me.

Sure doesn’t look like the original

Contact you local EBMM dealer about getting one.

Good luck., Glenn |B)

Hello,

I finally got hold of an original Tremolo arm from Ernie Ball but it doesn't fit, unfortunately I can't get hold of somebody from Ernie Ball so I am left clueless. My serial number is saying that my guitar is built in 2020 and the Ernieball Webshop states that the arm I purchased fits all Petrucci guitars made since 2011. So I really don't know whats different about my guitar.....I am really dissapointed in Ernie Ball for spreading wrong information. It is annoying when the trem bar is hitting the volume poti all the time. I don't think this was in John's interest. Any ideas?

Best regards.

Fabio, sorry to hear you are still having problems. If you have the correct arm on a legitimate and unaltered EBMM JP model, there should be absolutely zero issue.

Suggesting the company is spreading misinformation or that they have been producing a signature guitar for JP for over 20 years isn’t in his best interests is way off base.

The initial arm that you had was absolutely not the correct arm.

It is possible that:

A) someone sent you the wrong arm by mistake - yes mistakes can happen.

B) you need to adjust the set screw at the back of the tremolo or

C) a previous owner messed with trem (hence why you received the initial trem arm)

My bet is that you need to "loosen" the tremolo arm hole, so that the new tremolo can fit into it's place. Use the previous tremolo arm, push the bar towards body and you should see a hole on a block that can be adjusted with 1,5mm allen key. Loosen it and try to push the new arm into it's place.
Picture: It's on the right corner. Sorry for unfocused picture.

The diagram below should help!

There is an additional screw we can call "D" that is not shown. It is located on the lower part of the brass block, in line with the holes the strings go through, and in line with "A"

"D" is used to set to the overall depth the bar can be inserted, so that the notch in the bar properly interfaces with retaining spring "C"

If "D" is missing or very loose, the trem bar can be inserted too far.

There is also the slim possibility that the tremolo bar is bent at the wrong angle, which would be a simple matter to correct with a bench vise.

A= Trem Bar Tension Adjustment (spin control)
B= Bar Spring Mounting Screw.
C= Bar Spring (this is what the notch in your trem bar hits to keep it in the trem)

For those with piezo, your piezo junction board is mounted on the opposite side.
