Neck and Neck
I’ve been asked about the thickness of the Epi Riviera P93 neck, in comparison with other Epi guitars. I’ve also measured the Epi Sharaton II, Dot Studio and Casino, and their necks are all very similar to the Riviera P93, within 1/32” for each measurement (thickness at 12th, width at nut, width at 12th). And they’re all the same 24 3/4” scale and 12” radius. The Epi Les Paul’s and SG’s have a slightly thinner neck (about 13/16” at the 12th fret), but the same width and scale.
Here’s some pictures and exact measurements (in inches) of the Epiphone Riviera P93 compared to my G&L ASAT III, Taylor 714CE acoustic, and a very thin necked old Ibanez 540SBC. Update 5/14/2011: added Vox SSC33.
All measurements in inches:
| Guitar | Thickness at 12th fret* | Width at nut | Width at 12th fret | Fretboard radius | Scale (nut to bridge) |
| Epi Riviera P93 | 31/32 (.97) | 1 11/16 (1.68) | 2 3/32 (2.09) | 12 | 24 3/4 |
| G&L ASAT III | 31/32 (.97) | 1 5/8 (1.62) | 2 1/32 (2.03) | 7 1/4 | 25 1/2 |
| Taylor 714CE | 39/32 (.90) * | 1 3/4 (1.75) | 2 5/32 (2.15) | 12 | 25 1/2 |
| Ibanez 540SBC | 13/16 (.82) | 1 11/16 (1.68) | 2 1/16 (2.05) | 16 | 25 1/2 |
| Vox SSC33 | 7/8 (.88) | 1 11/16 (1.69) | 2 1/16 (2.05) | 12 | 25 1/8 |
* Taylor 714CE thickness measured at 9th fret since neck joint to body begins at 12th
