Yamaha SG-2000

First introduced in July 1976, the Yamaha SG-2000 represents, in my humble opinion; the epitome of Japanese solidbody guitar craftsmanship. It's no wonder then, that in its 1978 catalog, Yamaha describes the SG-2000 as being targeted towards "those who demand the very finest in both feel and sound." That being said, let's take a look at some of this guitar's distinguishing features.

Body
  • Five-ply binding
  • Carved, "mildly figured" three-piece maple top
  • "T-Cross maple and mahogany construction:" laminated maple and mahogany body, with the grain of the center section "set perpendicular" to the sides
  • Contoured back, top waist "scoop"
  • Deep double cutaways 
Neck
Three-piece mahogany/maple/mahogany laminated neck-through design

Fretboard
Bound black mahogany (not ebony), 22 frets, 24.75" scale length, 13" radius, mother-of-pearl "split-wing" inlays

Headstock
Five-ply binding, "double-dipped shape," block lettering logo, three-piece floral inlay.

Hardware
  • Gold-plated 
  • Fully adjustable bridge rests on two thumbwheels that screw into a recessed solid brass sustain block/plate
  • Tailpiece features a "harp and scroll" motif
  • "Precise torque" tuning machines (15:1 ratio) with "kidney shaped" knobs 
Electronics
  • Two volume pots, two tone pots (no push-pull coil split function), 3-way toggle switch
  • Pickup, switch and control cavities fully shielded with shielding paint
  • Two "powerful open-type" Alnico V humbuckers with "individually adjustable polepieces." Three machine screws allow for pickup height and alignment adjustments ("tri-mounting")  

The tobacco brown SG-2000 featured today was in particularly bad shape when sent to me; most probably due to prolonged neglect and (I suspect) abuse. Grime, rust, crud, tarnish, dings and dents was the order of the day here. On the plus side, I noted that the guitar had been recently been refretted and fitted with a bone nut. The electronics were a tad noisy, but this was soon cured with a few squirts of electrical contact cleaner.

Perhaps the toughest task I had to deal with was removing as much rust, crud and grime from the gold-plated hardware without taking off too much metal. Thankfully, I managed to accomplish this via electrolysis. Then there was the black mahogany fretboard, suffering from years of solidified sweat and grime caking the wood in between the badly tarnished frets. It took lots of careful scraping, lighter fluid, lemon oil, 0000 steel wool and Autosol to get the job done; but the results were worth it.

After reinstalling the hardware, this baby was given an all-round wax and polish, strung up with 10s, and plugged into an amp for a final check. Boy, did it sing!

1997 Gibson Les Paul Custom

When this guitar arrived at my doorstep, I was thrilled beyond words. I mean, this was the very first Les Paul Custom I'd ever worked on. Out of curiosity, I took a few pics and emailed them to Gibson Customer Service. Within 24 hours (bravo GCS), they replied that the "pictures and serial number" were "consistent with a Les Paul Custom model in Ebony finish, made on the 202nd day of 1997 in Nashville, TN." So, what I had in my hands was the real deal, and not a well-made knockoff. Besides the obvious, I've managed to ascertain a number of specs, thanks to the Gibson Guitar Board.

Body:        Mahogany/carved maple top
Neck:        One-piece mahogany/1959 rounded LP shape
Fingerboard:    Ebony/22 frets/24.75" scale/mother-of-pearl block inlays
Nut Width:    1.6875"
Pickups:    Alnico Humbuckers: Neck - 490R/Bridge - 498T
Controls:    2 volumes/2 tones/3-way switch
Hardware:    Gold
Bridge:        Tune-o-matic/stop bar tailpiece
Binding:    "Sumptuous multiple binding" on body/neck/headstock
