Are you playing in a band? Or just playing at home? And then ....... do you like a more open drum sound (with overtones and sustain), or do you like a more 80's thud sound ?????I have a 70's Pearl fiberglass kit that I am in the process of putting new heads onto. I have a few random heads that haven't been played on that have been gifted to me by a kind soul. I am about to work on the 16" floor tom.
If you're gigging, a more wide open sound will cut thru the mix better. You won't hear the overtones over the band. But if you're just at home, and trying to dial in that perfect sound ...... you really just gotta experiment.
I gigged a Vistalite kit for a few decades, and those are second cousin to fiberglass. I ran Pinstripe batter, and Ambassador (very similar to the G1) reso. Perfect balance (for me) of volume and sustain.
The EC Reso ...... it's a single ply ...... I'm not sure how much muffling is built into it. On my Slingerland kit, I'm running Pinstripe batter and CS Black Dot reso. I'm thinking the Evans EC is gonna sound a bit like the CS. A little overtone control, but not much. My Slingy's have plenty of slam.
Now ...... I've gotten used drums come to me, and they had Pinstripe batter AND reso. Not my thing. A little too much muffling But hey, it was working for the past owner.
