remo coated ambassador is equivalent to Evans G1 coated. Not that they give the same sound. I read that G1 coated gives a cleaner sound and has better coating (but in doubt ako sa coating ng evans). Haven't tried either on my snare tho.
evans hazy (200/300) coated snare drum head - This is the snare side head or resonant head of evans. Remo's equivalent product is the Ambassador/Diplomat snare side.
Ang gamit ko ngayon Evans Power center reverse dot over Hazy 300. Its basically an Evans G1 with a thin round film about 5 inches in diameter at the center underneath the head. Sayang walang picture nun...
I really love the sound of it. Gives a more focused crack when hit at the center and reduces ring. Gives a ringy slap when hit outside the area of the DOT. Parang Evans Power Center or Remo controlled sound sya na hindi masyadong namumuffle ang ring.
Unfortunately, yung mga snare heads ng evans dito ay kasama lang sa pack (G1,G2 clears), bulok nga! Kaya mag-Remo ka na lang. I've heard remo ambs on snare drum at gaganda ng tunog. But since its one ply 10mil (like evans G1) medyo ringy sya, something that might bother you eventually.
ambassador on toms is a good idea. Matibay naman ito basta maayos kang pumalo. Kung maganda ang drumset mo, lalabas ang tunog nya sa single ply heads kasi hindi namu-muffle yung tunog. Again, you should try it. If you play rock, better stick with G2, EC2, Emperor, or Pinstripe.
