A very useful product for smaller kits.
I installed this on my 16" Pearl Midtown bass drum and i was delighted with the results.
Firstly, It impacted positively on the sound of my bass drum. It gave a punchier sound as it allowed the mic to go closer to the head.
Secondly, it added to the aesthetic of my drum kit as it was silver like my hardware.
I would like if the instructions were clearer about application. Th company want you to also purchase a head cutter but i used a craft knife and had no problems although I wondered would the cut be cleaner with their cutting tool.
I would highly recommend this product. simple but effective!
