Yamaha TX416 TX Rack with 4 DX7 modules

Yamaha TX416 TX Rack with 4 DX7 modules For Sale. Pro-serviced. All old batteries have been desoldered and replaced with new ones. Each module has had the same standard set of patches reloaded into it. You'll need to do this to any TX rack that hasnt been serviced in recent times. Some people are happy with just one DX7. This is FOUR original DX7s in a rack. Play them multi-timbrally, or stack them all for one massive sound.  The sticker on the back of this unit says Yamaha TX216, which may or may not mean that it started out as a 2 module unit and was eventually expanded to 4. Either way, it shouldn't matter cause now it's a tx416! :)
