@tsp17...Looks like you've found the pickup-amplifier 'sweet spot' for your new Eagle. Awesome!
It's interesting that your increasing the midrange on the amp helped bring out the tone you were chasing. Your jazz heroes of the 50's and early 60's mostly played through amps with a mid-hump (i.e. Fender 5e3, Gibson GA models in particular). Then in the mid 60's Fender introduced its blackface, mid-scooped blckface rigs. That sonic change was evident in Kenny Burrell, George Benson and many other jazz guitarist albums of that era. I find myself boosting the mids a bit when playing archtops vs. semi or solid body guitars.
Have fun!
