Epiphone volume and tone controls

Your guitar was made in 1989 in Korea. At that time it was probably made in the Samick factory.

Sounds like perhaps a Les Paul Special II, but more detail is needed to say for sure. There was a lot of variation in their Les Paul models. Posting a photo of both sides and the headstock is best.

-Has the guitar any binding, and what colour?
-Is the back of the guitar white or all black?
-Exactly what is on the front of the headstock, 'Epiphone', the 4-diamond logo, anything else?
.

the switch, has three positions. Typically forward or up will be your neck (or rythm) pick ups, only and will work with one volume knob(usually top right as your looking at guitar), and one tone knob ( top left as your looking at the guitar). when the switch is in the far right or all the way down position, that will be the saddle (or lead) pick-ups. And that works with only one volume knob(bottom right as your looking at the guitar) and the corresponding tone knob. when the switch is in the middle position, botjh volume knobs work and both tone knobs work. You've gotta kinda play around with them to find whatever sound yopur looking for. and tone knobs are very subtle in their changes. good luck

That is near fatal... you might find a Luthier that could repair it. I have repaired three broken neck instruments myself, an acoustic bass, acoustic hollow body, and a banjo... it is NOT fun and requires great care. The strains on the neck from string tension cause a lot of force that tries to re-break the neck.

Most likely it is wired like most Gibsons. The volume knobs are the two at the neck end, the tones are the two nearest the rear. The lower two are volume and tone for the bridge pickup, the upper two are for neck pickup. Switch down is bridge or lead pickup, switch up is for neck or rythym pickup, and centre position is both pickups one, where all knobs can be used together.

Adjust this using the EQ on the amp and to a lesser extent the tone controls on the guitar.

Often people boost the bass way up causing this problem.

Epiphone is a budget conscious gibson. And probably not made in the USA.
1957 - Gibson's parent company, CMI, buys Epiphone for $20,000, originally intending to harness its upright bass operation, but ultimately reviving the Epiphone name on guitars. A full line of newly designed acoustics and electrics is unveiled in 1958, and two years later Epiphone production moves into Gibson's factory in Kalamazoo, Michigan.

1970 - In the face of foreign competition, Epiphone production is moved to Japan. Through the 1970s and early '80s, the Epiphone line has little continuity, although it maintains respect as a quality import brand.

1983 - Epiphone production is moved to Korea.

1986 - Henry Juszkiewicz, David Berryman and Gary Zebrowski acquire Epiphone and Gibson. The Epi line is soon expanded to include traditional models like the Sheraton, Emperor and Howard Roberts, along with Epi versions of Gibson classics like the Les Paul, Flying V and Explorer.

This will help for starters:http://www.epiphone.com/images/EpiOwnrsManul.pdf This site has good info in the discussion:http://www.thefret.net/showthread.php?t=4728 There's info here too:http://epi.p3net.net/bbs/index.php.

This is exactly how any 2 pickup, 2 volume, 2 tone, three way switch guitar would be wired from the factory. Best of luck!
