The Roland PD-125BK includes Roland's latest dual-triggering capacity, resulting in more even and accurate sensing between the head and the rim. Using Roland's brand new sensor mechanism, the PD-125BK gives you the most accurate triggering possible. PD-120BK has true rim shot capabilities - including the actual "rim click" sound - on the toms! (when used with a Roland TD-20 sound module) The new black finish compliments Roland's new V-Pro and other V-Drums series.
