I decided to purchase a Roland PDX-12 pad to expand the set of my Roland TD-17KV drum kit, which I have been using for almost 5 years. The set of this drum kit includes a Roland PDX-12 pad, which is used as a snare drum pad. I added a Roland PDX-12 pad as an additional floor tom pad. This pad has a large size of -12 inches, which is very close to the full-size snare drum. It is very comfortable. The pad has a mesh work surface on which it is comfortable to play, the surface is very quiet when playing. The pad has two sensors that allow you to adjust two different sounds to the center and to the rim of the drum. As I wrote above, I have been using the Roland PDX-12 pad as part of the drum kit for almost 5 years and during this time I have not had any complaints about the operation of this pad. The Roland PDX-12 pad is made of high quality and has a low weight with a large enough size, it is very convenient when using a drum kit at live performances.
