Product Name: Yamaha DTXPL Eletric Drum Set FOR PARTS READ buying PLZ
selling as is / parts. Bought this locally and I know nothing about drums. Just want to get close to my money back. Can't get it figured out on how to get it to make sound. Not sure if I had cords in wrong places or what but I don't think the guy sold me a bad set because he was super friendly and it was porch pickup and he told me to send him videos of me playing once I get it hooked up. Just haven't made time for it like I thought i would. Please see pics as buying they show condition well. The main power / control panel powers on but I can't get it to make sound. Therefore selling for parts only. The pads alone I've seen sell for 100 Ships out same or next day Will have to disassemble when shipped FYI.
