Re: Remo Ambassador coating wearing off...
Remo's coating does seem to wear faster than Evans and Aquarian.
Remo's coating is also the warmest sounding in my opinion because it is softer than the others.
I have good luck with coated Ambassador heads on my snare and toms. They do wear but they last a long time for me.
I love them on my Jazz kits because they are so warm sounding and sensitive to the lightest touch.
I use coated heads by Evans and Aquarian on my Rock, Country, and Pop kits because they are brighter sounding at looser tensioning.
This is just my observation, Your results may vary from mine.
