Smile Gotoh Bridge into a 2003 JEM555

I'm not happy with the tuning stability of the original trem supplied with this guitar so I plan to upgrade to a Gotoh (spec attached - hopefully).

One question/ concern has crossed my mind however; will the lions claw allow for serious pull up of the whammy bar (~5th) or will the extra length of the trem get stuck in the claw route?

Has anybody made this swap and experienced a problem with the whammy movement being reduced, or did it work out fine?

Are there better trem options that have tuning stability but aren't as long as the Gotoh do as not to interfere with the claw operation?

Any ideas or thoughts highly appreciated.

Re: Gotoh Bridge into a 2003 JEM555

see if the graphtech floyd will fit??
i stayed away from them for years, even being a graphtech fan, because the body is cut perfectly square and it looked funny......that was a mistake! when i tried one, i instantly fell in love. sound great, stay in tune, and half the price of floyd or schaller. not sure about the lions claw though. it is a pretty short bridge

as far as reduced movement, i have an rg deluxe that when set up properly, the bridge is sitting on the shelf for the studs, all original hardware.........what a disappointment!!

Is it an Edge III in there currently? Why not put an Edge Pro instead?

You can shorten the overall length of a Gotoh by using Floyd Rose locking screws. They are 5mm shorter.

You need to shim the neck at the neck pickup end of the pocket to raise the trem up.

Your guitar has an Edge-ProII. The Edge-Pro is a direct drop in- no modding necessary....... just add locking studs and inserts to complete the package.

Also, disregard my post about dropping an OE into the guitar on your other thread (FSK101)......... I didn't read this til after replying to that one.

For the cavity I understand, but wouldn't this require the stud anchor holes' diameter to be enlarged? I remember reading the Edge Pro II stud anchors having 10 mm OD compared to the 11 mm OD diameter of the Edge Pro anchors, is that right? Also, if the stud anchor holes are to be enlarged, can the Edge stud anchors and locking studs be used with the Edge Pro knives?

Thanks,

Yes, your correct. the anchors for the locking studs are slightly larger and would require a larger bore to fit.

Yes, the locking studs will work great with the EP knives.

Re: Gotoh Bridge into a 2003 JEM555

Thanks RGTFanatic.

Barring any lathe or similar large equipment what would be the best way to enlarge the holes? I guess with only 1mm of enlargement required, one can sand the bore wall, but how to achieve the accuracy needed? Any known methods to enlarge the bore without any power tools?

You don't have a hand drill? If you werer careful taking a mm out shouldn't be too hard.

To be honest, I did it in 5 mins using 3 different drill bits by hand.

Can't remember which 3 though, I'll get back to you on it.

edit: FWIW...... you can see what the upgrade studs look like in this thread I did. These are the ones I did in 5 minutes.

Thanks for the replies, I've gone with the Gotoh and will update once it's fitted regarding claw functionality.

Yes I do but I wouldn't want to take too much out of the body, just because I couldn't judge the required depth while trying to keep the drill as vertical as I can to keep the bore straight. I wanted to see how the more experienced members do it.

Thanks. I remember seeing your thread about your nephew's guitar. Right now it doesn't look like I may have a tuning problem with my new-to-me guitar with EP II, but i'd like to know what bits you've used just in case I need to change it in the future. After all the guitar I have is a 2005, and I don't know how long it would be before I need to replace the bridge.

It would be interesting to see how it fits, as i have the same cavity and would like to see how Gotoh fits in there.

Re: Gotoh Bridge into a 2003 JEM555

I have had the bridge fitted. It is not exactly a 'drop in' replacement - 15mm had to be ground off the bottom of the brass block so it would actually fit within the guitar body and the locking nut is not compatible (so left the original on).

Pictures below:

Re: Gotoh Bridge into a 2003 JEM555

Forgot to mention that a couple of mm had to be shaved off the trem cavity - although I guess this might not be the same for everyone... if the manufacturing tolerances in the Korean factories are big?

Re: Gotoh Bridge into a 2003 JEM555

Very good. Although I would have left the cavity off so I could benefit from the tone from the extra mass of the unmodified block.
