Edward,
After starting flat, do you primarily use the ES2 or the DI or the mixer to EQ the sound? If you use more than one of them to EQ which one do you start with first?

Starting from flat EQ, all the above depending on what you're trying to accomplish. Think about where the frequency center is on each device:
- Most mixers will have Bass centered at 100Hz and Treble centered at 10kHz (and some consoles will write it on the channel strip, eg Bass=80 and Treb =12k).
- The above is significant because EQ at the DI is centered on the frequencies more useful to the acoustic guitar. So using a parametric (sweep EQ) you can "find" that mid-bass freq that lends to a flubby, boomy bottom, likely around 500-600Hz, so reducing here at the DI is better than attenuating the Bass at the board which is a very useful and solid 100Hz. Not to mention the bass control on the Taylor is quite effective and useful.
- Same with the treble: the 10k knob at the console to a guitar is like "presence" or "air" whereas lots of that
guitar top end you want to affect sits in the 3-4kHz zone. So a bit dull or too zingy, go for the 10k at the console; but the "top end" tone of your guitar, go for the treble on the ES2 and/or the knob on the DI and listen carefully which is the "treble" tone you really want to adjust ...it'll be pretty apparent that each of these treble knobs will have their own tone (their own freq centers), so choose according to your ears.
- FWIW, this is one reason why I like the Baggs Venue: two parametric bands plus Bass and two Treb knobs ...powerful tool, this. But other DIs are quite good, as well!
Hope that helps you a bit
