Besides the amazing wood drying process on PRS guitars and outstanding craftsmanship, another characteristic that I don’t see advertised as much is the wood grade used in Core guitars. I believe PRS use a lower density mahogany for their core guitars, like you find in the Custom Shop of other manufacturers. There are two reasons I come to this conjecture. One is the weight on the guitars. Even a thicker body 594 usually stay bellow 9 lbs (with a few exceptions). That’s weight relief or solid custom shop territory. The other reason is the gain on the mahogany of core guitars. Mahogany has an almost dashed looking grain. These “dashes” tend to be darker on lower density mahogany than higher density ones. The grain on the mahogany used in PRS core guitars look similar to the grain used in other manufacturers custom shop. So here is what I’m talking about, From Left to Right, PRS 594, Custom Shop and Regular Production guitar. Note how the grain on the 594 and the Custom Shop is more defined than the regular production guitar o the far right. Also the weights are 7 lbs 8oz, 8 lbs 10.5oz, and 9 lbs 3oz for the DC 594, Custom Shop and regular production guitars respectively. I attribute the difference in weight between the 594 and the Custom Shop to the DC 594 having a thinner body than the Custom Shop and being a double cut, which I conjecture have lower mass on the upper bout relative to single cut guitars. Most SC 594s I’ve seen seem to be in the same ballpark as my Custom Shop. Anyway, I think this corroborates with what some people have say that Core PRS guitars competes with other manufacturers Custom Shop guitars. At least in the grade of wood used in the construction of Core guitars, that seems to be the case. It is believed that lower density was used on older instruments. The trees were grown slowly over the years, which is believed to be correlated with lower density timbers. With the sustainability issues that we currently face, trees are grown rapidly, which results in higher density and therefore, heavier timbers. This is what led some manufacturers to sometimes resort to chambering the body of guitars. The lighter, less dense timbers became more scares, and therefore more expensive for guitar making. In summary, PRS is using premium woods to make their Core guitars. Combine that with their level of attention to detail, workmanship, perfectionism, and time consuming build and preparation process, you understand why PRS core guitars are so amazing.
