Yamaha Hybrid Stage Custom Pack. A special set that will turn your acoustic set of drums into a quiet, electronic set. The REMO SILENTSTROKE mash membranes have similar characteristics to the classic membranes, but they are absolutely silent. They are set up without any problems like the classic ones and can be replaced at any time. The signal is captured using the DT-50 trigger, which can also be used with classic membranes to create new sound options. Hybrid box includes DTX502 module and power supply, DT-50 K bass trigger, 4 x DT-50s snare and tom triggers, RHH135 13'' hi-hat pad, PCY135A 13'' and PCY155A 15'' cymbal pad, module clamp, and all the necessary cables.
