Mini Core style guitar and bass pedal tuner with large HD colour diplay for easily visible tuning status. The signal throughput can be set to true-bypass (TB) or buffered (BF) where the output is muted during tuning. An additional buffered mode (BFM) keeps the output unmuted during tuning to keep showing tuner status whilst playing live. Three different display modes can be selected, including a strobe simulation. Modes for Guitar, Bass or Chromatic tuning can be selected and holding the same button allows A4 tuning frequency to be set. Overall, an ultra-compact yet rugged pedal tuner with maximum display for stage performances.
