    OK. I am a real newby when it comes to electronics. I am ordering some 500k pots for my 1992 Classic Les Paul. I tried to measure the pots, but I don't know how to get the metal plate out that they are stuck to.

    Does anyone have a (specifically) 1992 Gibson Les Paul Classic and know if I need long or short shaft pots?

    Thanks

    Pretty sure they are long shaft, and you can always back off the long shaft pots if you need to for the perfect fit. Can't make short shaft pots longer!

    All Les Pauls since about 1976 are long shaft EXCEPT Historics. Your Classic is long shaft. It has nothing to do with the mounting plate, it is how the control cavity is routed.

    Thanks for the info. As you can probably tell..I don't know what I am talking about. I am no electrical guy, but I would like to be :). Thanks again.

    My 1990 Classic's cavity was routed so that you could use two short and two long pots, and came without the mounting plate. Strange.

    Yes there were a few early Classics and a few early 90s Reissues without the plate, but the plate was the norm. Probably the long shaft ones were the inboard (neck vol/tone) pair?

    From my past experience with wiring orders it is best to pull them out and check to make sure. If you guess you will probably be wrong. LP Customs, Supremes and many 70's Standards take the long shaft Pots. Other Standards, many classics(not sure about yours), SG's 335's will use the shorter shaft pots. Short shaft pots have threads that are 3/8" long to fit through the wood as the long shaft will have 3/4" long threads. I have contacted Gibson about this and it varies from guitar to guitar, year to year. Some take 2 long 2 short, best to check to save any hassle.:)

    GOTTA LOVE THAT GIBSON QUALITY CONTROL!!! I called them once on a serial number...The answer was "Well it could be a 1988 or 1998. Sometimes we have reused serial numbers." I love my Les Paul, but it yeesh!!!

    It is almost like their assembly line is "Well let's see what is in the drawer when the guitar rolls by!

    I have owned MANY Standards and Classics from the 80s and 90s and they ALL had long shaft pots. In fact, as far as I know ONLY Les Pauls (non SGs) use long shaft pots, all other Gibson use short shaft, as do the vintage Les Pauls (through about 1974-75) and the Historics. But, as in anything Gibson, NO statement is 100%

    If you want some minor overkill, Ted Weber carries long-shaft 250 and 500k pots that have 1" bushings (LP's use a .75"). He includes two sets of nuts and washers so that you can adjust the depth to taste. His pots are foreign made; but to his specs, including a 20% taper on the long-shafts. I've used quite a few of his pots in my amps and have been impressed, especially on price. They are better built and feel smoother than the Alpha's IMO.
