Thanks, Brent. *I was really curious since my RGPR1 seems quite similar to the 1880, except mine does not have the single coil, and a few other differences in detail. *Deeply flamed natural maple top, cream binding, and it has the same big neck with
ebony board...which seems to make them cousins. *I'm not 100% sure about my pickups. *I had assumed TZ/AN, but with further comparison I'm questioning that. *It could be other factors, since it does sound different even unplugged. *The top is actually slightly thicker on the 3120, and I wonder how much difference the bit of extra maple on the neck makes in tone?
To me the 3120
bridge pup sounds great...rich tone with lots of harmonics, and the "in between" sounds are twangy enough and quiet. *I was never happy with the PAF pro in the neck because I prefer a fatter tone there for leads (ala Santana). *Notes are well defined due to the direct mount pups.
The more I compare them directly I'm surprised at the differences. *By comparison my RGPR1 is a warmer & fatter sounding...even acoustically, it doesn't ring as brightly as the 3120, but seems to sustain more powerfully. *Plugged in the individual notes are even more clear and articulate, whereas the 3120 the notes sound fizzier (not bad, just different)...I'm guessing due to the rose board. *Distorted chords are much tighter and a bit darker on the RGPR1 at the bridge...from Dimarzio's site it almost sounds more like an Air Zone type curve...the harmonics don't squeal as readily as with the 3120. *The neck pup is definitely chunkier in the mids and bass...I really like that. *The PAF pro is nice in the neck for chording, but I use the neck more for ballsy lead tones...but I digress. *The RGPR1 has position 2 (1 being neck) as parallel, whereas my 3120 is split.
Anywhoo, maybe I'm being too analytical...I didn't notice the differences at first, but a little while switching back and forth was telling. *Either way, both are fine guitars!
