SUPERNOVA tuning pegs / MACHINE HEADS

HI THERE

 

I own a 2001 Epiphone Supernova (Man. City Blue), and I would like to change it's machine heads/tuning pegs. I was thinking of some self-locking rotomatic chrome Grover tuners, but I don't want to mess up the holes on the guitar, so I tried to find what pegs suited my guitar best. All I found was that the Grover tuners I want to buy are 18:1 (no idea what that means). =D> Simultaneously, I've unsuccesfully been trying to find on the Internet whether my epiphone came originally with 18:1 tuners straight from the factory, but I couldn't find it. I was wishing if you could give me a hand here, and tell me whether my epiphone supernova comes with 18:1 tuning pegs, and if those rotomatic grover tuners are suitable (and if they are a good choice) for my Supernova electric guitar.

 

 

Sooo.... Did the Epiphone supernova came from Korea brand new with 18:1 tuners?????

 

Regards from Argentina,

I'm not sure what your guitar came with, but the 18:1 means that for every 18 revolutions of the tuning peg,

the string post turns one revolution. A very fine ratio.

Most Fender guitars come with a 12:1, or maybe a 14:1.

My Epi Les Paul, made in Korea in 2008, came with 18:1 Grover tuners.

To check your tuners turn the peg, counting how many complete turns it take to turn

the post one complete revolution.

Thanx man

 

I just checked it out, and I can say almost for shure that my tuning pegs are a 14:1

 

The thing is... If I buy the "3+3 rotomatic self-locking tuning pegs 18:1" by Grover... Will I be able to install them withouth making any modification to the guitar? Cause I don't wanna screw anything up, or make a bigger hole or that kind of things some guys do...

 

My big fear, on the other hand, is to buy them and realise they are useless for my guitar... here's the "ebay" (what in my country would be ebay) link:

Thanx a lot,

I just unscrewed one peg and measured (remember we have millimeters down here in Argentina) the diameter of the peghole, its almost (if not) exactly 8mm. 8 mm are about 0.31496063 inches

 

The thing is... I don't understand that language, such as Hole size: 25/64" 3/8" etc. Would someone "translate" this for me please? Or just tell me which Grover tuning pegs/machine heads I need so as not to change my 0.31496063 peghole.

 

Thanks a lot

As you may be aware, the US has never adopted the metric system of measurements.

It looks like the locking Rotomatics (25/64") will not fit your guitar without drilling out the holes. It appears that your holes are 5/16".

 

I suggest that you send a private message to a member named "TWANG" - he will be happy to help you sort this out, as he is extremely knowledgeable regarding Epiphone modifications.

I sent an e-mail to Gibson's Customer Service, and here is their reply to my question:

 

Hi,

 

Thanks for the email. This model had Kluson style tuners with metal buttons. The hole diameter is 11/32” and the ratio is 15:1. Thanks again.

 

 

So there I have it, I need 11/32'' tuning pegs if I don't wanna drill my guitar's pegholes.

 

Thanks to all of you who spent time in order to solve my inconvenient.

Francesco, maybe I´m 10 years late but, as  Ron mentioned, US never adopted the metric system, given "said" this, the measure:  25/64  refers to the mathematical nomenclature to inches in fractions. You can basically use an inch fraction calculator to change to the decimal notation in inches or millimeters.
