NUX Flow Tune Pedal - Blue MKII

Mini Core Tuner

A compact yet battle-ready guitar and bass tuner pedal built for the stage. Featuring a large HD colour display, the Mini Core delivers instant, crystal-clear tuning feedback at a glance—even under bright lights.

Signal routing is fully flexible with three output modes:

• True Bypass (TB) or Buffered (BF) with auto-mute during tuning

• Buffered Monitor (BFM) mode keeps your signal live while tuning, letting you stay in the mix and monitor pitch in real time

Choose between Guitar, Bass, or Chromatic tuning modes, with three display styles, including a smooth strobe simulation for ultra-precise tuning. Hold the control button to quickly adjust the A4 reference frequency for alternate tuning setups.

Ultra-small footprint, rugged construction, and maximum visual clarity—this is a Mini Core tuner designed for serious live performance.
