I got a free remo falam slam bass drum patch with a remo powerstroke head. I put it on and played it for a while. A couple months after this, I got a double bass pedal and had to get another patch. I purchessed a package that came with 2 remo falam slam impact badges and realized that the one that came with the head was different. I applied one of the badges to the head where the other beater hits. I tried it out and each of them sounded different. The one that came with the head seemed more cheaply made and was starting to wear away in the center. I used some rubbing alcohol to take it off and the badge came off fine but there was still sticky residue left which I am having trouble getting off. Will decrease the sound quality of my bass drum head if I just leave the residue and apply the new badge right over it? Does anyone have any advice? Thanks.
