・ Used as a spare or sub machine. There is a specific LCD issue with the TD-12. As shown in the image, it displays when it's working well, but it often becomes scrambled or disappears. When adjusting the settings, I repeatedly turned the power on and off until the LCD displayed. ・ I checked the sound output of all triggers with headphones. I also checked the rim sounds. I think there are no noises or delays, and it's good. ・ The buttons respond when pressed, but sometimes they don't respond unless pressed firmly. ・ There is a problem with part of the red number display on the left side of the LCD. ・ Of the three knobs on the top right, the middle "phones" knob is not working well. It's too sensitive, and the volume changes drastically with just a slight turn. (It outputs without problems if you keep turning it a few times and stop at a good point) ・ I haven't checked the connections for the mix in and MIDI terminals on the back. ・ There is age-related deterioration such as minor scratches, but there are no cracks or breaks. ・ This is an auction for the main unit, cables, and instruction manual only. ・ I will list this as "junk" because there is a possibility that I have overlooked other issues. Please do not purchase if you are looking for perfection, as this is over 15 years old.
