Hi guys, sorry so late in responding to your awesome responses to my query. Yes, it was the XLR floor box k&k preamp I tried. I also have a Fishman SA220 soloamp. It has it's three band eq. I find with my 514ce (hog/cedar) that it's very warm sounding, but through the solo, lacks the high end sparkle unless I really dial up the High EQ knob, almost all the way in fact. Which is surprising because I feel like the solo is already voiced with some sparkle, but it could be my cedar top combined with the new ES. But when I went through my friends K&K xlr preamp/DI, it gave it the sparkle without having to add so much high at the EQ level, it basically made the guitar sound more like what I hear when I'm playing unplugged. Anyway, I can get a similar effect by jacking the highs on the soloamp, but I think I like the voicing if the K&K xlr preamp/di so I may go with that. Thanks for your responses!
