Kinda? Someone can correct/add on to this but:

FA = Fender Alternative series (“beginner” series/line) -laminate guitars of pressed fiber

CD = Classic Design series - spruce tops, mahogany body

PD = Paramount series -solid mahogany wood top and body

The “E” At the end means they’re electric (likely Fishman pickups)

Dreadnought will be the body shape. This is the big American acoustic shape with deep low end.

Not sure what the individual numbers mean.

I've been perusing their website for a little while now, and there is a rough pattern:

At least for acoustics:

• The first two letters are the series. This is the most variable component, but follows some loose guidelines:
  • The initial letter is often indicative of what what onboard electronics that series of guitar comes with, even if the particular guitar doesn't have them (C guitars come with Fishman CD-1, F come with Fender, P come with Fender/Fishman sonitone plus). This letter is sometimes omitted (see the simple D10 dreadnought)
  • The second (or first, if there is only one) letter generally indicates the body style. D is dreadnought, C is concert, B is bass (or banjo!), O is orchestra (?)
• The number generally indicates quality. Bigger number more expensive within a series.
• S after the number indicates a solid top (no S indicates laminate)
• C after the number indicates a single cutaway body
• E at the end indicates that the guitar has onboard electronics

I always thought Ibanez was the worst for this. "What guitar would sound good on this track? I know - the SEW761CW! Or, if not, maybe a AZS2200F?"

A desperate corporation that can't innovate anymore throwing things at the wall to see what sticks?
