Just found that idea.
http://www.youtube.com/watch?v=UYQujazVBQQThe poor stock quality heads with LP drums can be improved by dampening the head on the underside. I use clear duct tape and I play with how much I use until I achieve the tone I like. Others use for dampening purposes: foam weather stripping, silicone, rubber cement and anything else that will reduce overtones. Afterwards, you may be able to achieve favorable tone.
Enjoy! The journey for better tone can take time but it is rewarding. Please share what you find when you find what works for you. There are so many different unique solutions to the same issues. When you find this, you might find that this can improve the tonal quality instruments you presently have or my own in the future.
In a humid enviroment I reccomend the Remo heads. The Fiberskyn and Skyndeep heads are great. They have heads specifically sized for the LP Aspire line that will work perfectly and improve the drums significantly. The Remo heads may need some dampening too to achieve the tone you may desire. The synthetic heads will be much more stable with their tuning than a natural skin in a humid enviroment after the heads settle in.
