Description Product Description The Node Model 8001 offers professional-level, 12-wheel (one strobe per scale note) strobe tuning at an incredibly affordable price. A streamlined interface allows quick-and-easy viewing of individual notes with its bright, backlit display. Scaled down and as compact as can be, the Node brings an easy to use interface to a complex process, with rivaling accuracy. The 8001 is a fully analog tuner, with all of the controls taking place in one general location. The control center is focused around the large Rotary Vernier dial for quick adjustment. Around the wheel there are adjustments for calibration, and concert pitch. With an onboard microphone, and a line in that's it. Nothing more to complicate the process.
