Autostrobe 490 Tuner in very good condition.

  • I have personally gone through all the buttons to make sure they work.
  • I have listened to the hum it makes on MAN mode (manual), and it does make a humming sound of the correct notes, but the Eb note sounds a bit wonky
  • The microphone works. I used my phones tuning app to produce 3 octaves of each note and it picked up all of them using the AUTO mode
  • The strobe disk spins clearly
  • The +2/-1 display button works and raises and lowers the octave when device is humming.
  • The LCD screen works and is easy to read.
  • The tuning is A=440hz, key of C, but you can change the key to Bb, F, Eb, and back to C
  • Does not include power cable, but uses a standard IEC AC power cable that you can buy for like $7 at Walmart.
  • This listing ONLY contains the tuner, nothing else.
