The One Control LX tuner is equipped with a BJF buffer developed by Bjorn Juhl, which can be switched on and off as desired. With the One Control LX Tuner, you get the best of both worlds: You can choose whether you want to use the high-quality BJF buffer and its advantages, or switch the unit to true bypass mode to avoid impedance problems with old school fuzz circuits, for example. 

The LX Tuner with BJF buffer features a Korg Pitchblack Custom tuning circuit and has an impressive three-dimensional tuning display that is easy to read from any distance. Four different display modes are available: "A Mode", "STROBE MODE", "HALF STROBE MODE", “Regular B Mode”. The reference frequency of the LX Tuner can be adjusted in 1 Hz steps from 436 to 445 Hz and it has a tuning range from 20.60 Hz (E0) to 4186 kHz (C8) with an accuracy of 0.1 cent.
