I like to go for the higher jazz tunings, really makes my toms stand out especially for louder music.
Tony, I'm going to give the non-cranked reso again. I normally go for a higher tensioned reso because I like the sound and response that it gives. My normal method of tuning the batter to where it sounds good and sings and tuning the reso till it goes "plink plink" has not worked on my Acrolite. I cannot tune this damn snare drum to my liking. After the 3rd Ludwig 14x5 Aluminum snare I'm starting to think that its me.
I'm going to try Steve's method, shoot for a lower reso and slightly higher batter, get out the drum key and really take my time with this snare. I have heard many Acros/400 Supras that sound wonderful so I know it can be done.
It's worth a try. I usually use a super-tight reso on most snares, but I have a birch 14X5 Tama for which that tuning method simply doesn't work. I have to use a looser reso on that one. Give it a shot with the Acro!
