Snareweight M80 drum dampener offers Medium to Heavy Snare drum dampening - 4 different settings... or, flip it up and off the head for none at all.
 
The M80 presents some weight on the head to help shorten the lower frequency hum and never sticks to the head like tape or gels. You can dampen in a snap or disengage even faster with the on/off magnet feature. Works with triple flange hoops, die-cast, s-hoops, angel hoops, true hoops, brass hoops, and 1/4" wood hoops.
 
See M1B for a more subtle dampener from Snareweights.
 
Leather thickness does vary between 1.5mm to 2mm.
 
Also works great on floor toms!!
