If it helps anyone. . . .
I've been playing with this EP 'G' string for over a week. Did my first serious gig on them last night. 4hr, piano trio, amplified w/ FC pickup. I have to say that it really performed great. This was a nice room that like playing in--nice acoustic sound. The EP was exceptionally loud. After, like, 2 sets it seemed to me to be a 'tense' string, that is to say a little tighter than the rest of my Spiro Mittel set. It spoke quickly, i.e. there was no need to really 'dig in' (like w/ Spiros) to get that note. The fundamental was all there. I didn't change a thing on my amp--except maybe to turn it down. I'm still getting used to the string, and it's still loosening up a bit, but wow. The main thing I noticed was during arco solos. I was so accustomed to really having to 'dig in' with the bow on Spiros during bowed solos. I started to dig in and it was WAY too much. The level of finesse with the bow on these strings is unreal. Now, I had been practicing with the bow ALOT on these strings, but the gig situation really taught me alot about how I was used to approaching Spiros. Alot less overtones. I'm actually considering now doing EP G and D and Spiro Mittel E and A. The G kicks ass, it's just a tad unbalanced (mostly feel-wise, but sound-wise, too) with this Spiro D.
I also agree with a previous post: first gig on it and my hands were TIRED at the end of the night. Can't wait for the next one, though.
