dcs81 Posted November 27, 2011 Share Posted November 27, 2011 Hi all- My wife got me a 1967 Epiphone Casino from a large chain music store, who sold it to her claiming it was all original. She paid about $2500 for it, and upon playing it for the first time I realized that one of the tone pot's wasn't working right. I took it back and they tried to clean it, but it appears to be shot. Does anyone have any idea if I was to swap out the tone pot what this would do to the value of the guitar? thanks! Link to comment Share on other sites More sharing options...
stein Posted November 27, 2011 Share Posted November 27, 2011 The best thing I would think is to measure what the other one is, and get one that measures as close to it as you can. I am curious what it is myself. I was trying to find info about what values where used when, and I honestly don't think it is common knowledge. My best guess would be 300k audio. The reason for the confusion is that I don't think it has always been. And to make it even harder, I have seen where some models of Gibby use 500k or 300k for a P-90 guitar. So, in other words, you tell us. You can measure them between the outside lugs and that should give a good reading. Also curious what they might say they are compared to what they read. If anyone knows more or different, please share. Link to comment Share on other sites More sharing options...
bonzoboy Posted November 27, 2011 Share Posted November 27, 2011 Your wife did all right on the price of the Casino as she paid on the low side of the value that could be up to $3,000.AS for the value of the guitar dropping with changing the pot:if you can possibly salvage the old pot it would be better,where pots and switches are commonly replaced due to wear and tear the value of the guitar wouldn't drop much as long as you replace the pot with one of the same value.If you could find NOS of the same pot it would be great.

Ti-Ti Posted November 27, 2011 Share Posted November 27, 2011 500K Audio taper for both volume and tone. <_< Link to comment Share on other sites More sharing options...
stein Posted November 27, 2011 Share Posted November 27, 2011 500K Audio taper for both volume and tone. <_< Is that the current spec, or is that what they actually used for that guitar in 1967? Link to comment Share on other sites More sharing options...
RaSTuS Posted November 27, 2011 Share Posted November 27, 2011 Is that the current spec, or is that what they actually used for that guitar in 1967? I was sure the current spec was 500Kohm audio tapers for tone, and linear tapers for volume, I have no idea of the '67 specs though. Link to comment Share on other sites More sharing options...
Ti-Ti Posted November 27, 2011 Share Posted November 27, 2011 As the Casino was equal to ES330 then http://www.gibson.com/Files/schematics/ES120T.PDF But I know there are several versions ... Link to comment Share on other sites More sharing options...

Do you or anyone else have any suggestions on pots, or brands of pots, or a place to pick up a similar pot? The store said they would get an "of era" pot, we tried 3 different times to clean and salvage the pot, but it seems to be shot. Thanks again for all the help people!

The BEST thing to do, is to remove the others (you have to do that anyways to replace the one) and look at what is in there. The volume SHOULD be the same value for both pups, as well as the tone values should be the same for both pups. There is a chance that the values for the tones will be different than the values for the volumes. There really is no reason to guess what is in there, sinse you have the originals. When you then know what you have, then it will be much easier to either find another that is the same, or determine what would be the closest replacement.

Lefty Bill Posted November 29, 2011 Share Posted November 29, 2011 What a fantastic find.. it's great to see that folks are still finding 60s and older guitars in fine condition. A vintage guitar that doesn't play, is just a display item, IMO. Replacing the pot with a decent quality new pot shouldn't be a visible repair, so it isn't detrimental to the appearance. Most reasonable folks realize that a guitar made decades ago is likely to have parts replaced in order to keep it in playing condition. You can keep the removed part in the guitar's case for posterity's sake. Appearance is a major value factor in the beholder's eye, so keeping the outside appearance as nice as possible would far outweigh replacing a faulty pot.. while keeping as much of the guitar as original as you can. It's possible to find a 1970s pot, but whether it will be authentic or not is one factor, while being in good working condition is another. Sitting on a shelf or in a drawer for all those years doesn't ensure that an unused pot will be perfect.. and it may be in poor condition. When it comes down to actually knowing if something is all original, there are grey areas, and only the first owner would know for sure (if they never lent it to a friend, etc). If it were in my hands, I'd put a quality pot in it (or all of 'em) and enjoy playing the guitar (saving the removed parts of course). If, or when it gets insured or sold, then it will likely still be in good playable condition.

stein Posted November 29, 2011 Share Posted November 29, 2011 I just read your original post again. I suspect it is just as possible that you have a loose connection as it is you have a bad pot. If you have never wired a guitar like that, they can be difficult to do without practice. It is somewhat of a chore fishing the components in and out, as well as fixing them up properly to have them fit to get them back in. You may want to consider taking it to a shop who is both skilled in that area, AND have knowledge and respect for vintage guitars. Those electronics ARE worth something and worth preserving if it is possible. Link to comment Share on other sites More sharing options...
