Well, dig this, everyone (regarding my 812ce/cedar top):
Today I switched off the body sensor (in my sublime ignorance, I didn't know Taylors had this switch until after my guitar was delivered). I jacked the Taylor into the amp's input A (which is a combo XLR input but I'm using a 1/4 inch mono jack currently), switched that input to "Low", cranked the amp's input gain way up, just short of max, set everything at neutral on the amp and guitar, and wait a minute....... "Mama Mia"..... it sounded really great! I use a fairly heavy (1.5mm---Gravity Axis) pick most of the time. The standard factory strings are on the guitar. I don't know what gauge they are.
(Note: on some amps with dual inputs, the EQ on the combo input (A in this case) is sometimes engineered for vocal mics....I don't know if that is the case with mine. On others, the EQ acts the same for both inputs. This amp has separate EQ controls for each input. )
I practiced a chord melody arrangement a few times, and then noodled around with a few melody lines, getting around the fretboard. After awhile, I rolled off the treble just a tad, edged up the guitar's volume knob, and it just got sweeter.
The sustain and clarity of this guitar almost everywhere on the fretboard is surprisingly good (except the low E by comparison----it's merely "normal"). I think it has more natural sustain than my Ibanez jazz guitar, even when you're holding a chord and letting it ring. Reverb? Who needs it? The natural reverb on the Taylor is all you need unless you want to sound like an empty high school gym. Feedback? None yet, but I haven't cranked everything to the max. using this 100 watt amp. This setup could sound very sexy with a little chorus, maybe. I can see myself possibly shopping for a really quiet chorus pedal.
