Tama ML12 Memory Lock

I use this cause one leg of my bass drum lost tension and i didnt want to buy new ones so i bought this as a cheap band aid and it does the job pretty well.
I don't know the material that's this is made of but it's super light, not like normal memory locks, don't know if that's a downside but so far the bass drum holds well with heavy beating.

I use these on all my cymbal booms to have a consistent setup and a fast setup time. They are very well made, but the angle isn't always exactly the same when you setup your cymbals. It's not off that much of course, but I would prefer more precision. I still do recommend this product tough. Much better then using a magic marker.

Very well constructed, robust yet small, and easy to operate.

There's nothing more to say... When playing with more than one band, when you have to set up the drums quickly, these little memory locks will help you to find the right spot for your toms in just a second: find your sweet spot in the studio, set the memory in the tom arm and next time you'll have the tom right there where you wanted it to be.
I can't live without it now honestly!

useful espcially for gigging drummers, sleek looking

Bought for floor tom legs.
I bought these for use with 10mm floor tom legs, which they work very well for, they are a great design because of the nut that is sat behind the square drum tension bolt and are a hinged lock so grip is excellent. Very good piece of kit.
