K&K Trinity Microphone Solo

I have Trinity Pro system in my first guitar. I wanted to upgrade from Pure Mini pickup to Trinity in my second guitar so that I can use both on stage. I bought the mic but it sounds much worse than the mic in my first guitar. I wrote to K&K and they replied that "We had to switch to a different mic capsule about 3 years ago because the ones we used before were no longer manufactured. I choose a model that we as similar in tone as possible, but it ended up with a little less high end".
For me, it lacks A LOT of high-end (~ 8dB or so) and the overall clarity I find in the old mic. This is a big disappointment since the high end was the reason I wanted the mic. I just can't simply switch between the two guitars on stage without additional/separate signal processing.
