For sale, a yamaha qy100 in perfect working condition with a switchable backlight modification. Switch has been added at the bottom right of the unit.

All functions work perfectly as do all inputs and outputs. And internal battery has been recently replaced so all in perfect working order.

The backlight modification was very well done and keeps the screen bright and very clear. Bit of a rare one this, don't see many with a backlight mod this usable.

The unit is clean and in great condition, with just a few age related marks and small scratches on the casing here and there. The lcd screen is clear and very bright and controls all function perfectly, one replacement screw in the back around where the backlight switch is housed.

Comes with a power supply, but can also be powered with 6 double a batteries.
