So I just ordered new Remo Pinstripe drum heads and new Evans Reso heads. My 12 inch tom is sounding extremely flat with no depth at all. But my 13 inch tom sounds really good and has a full sound. I just cant get the 12 inch tom to sound full and not flat (the reso head is also flat). I have heard to tune your reso head higher or lower than the batter head, but how higher or lower? If anyone has any tips as to help me with my drum crisis, I will be happy to hear! Thank you.
