Latency-free Tuner Plugin with Fine-tuning Display and Output Dim.
Precise. Easy. Fast. This plugin tuner will let you tune your guitar or bass faster and with maximum precision. Simply rely on the LEDs and your guitar is good to record the next hit.

A unique little feature like the Output Dim proves that Brainworx have managed to improve even such a basic every-day thing like a guitar tuner. Try it to believe it. Sell your old tuner on Ebay. ;-)

If you’re a guitarist or producer who wants to play your guitar straight into his DAW system , you’ll love the hassle-free operation of the bx_tuner. Chromatic tuning for any guitar or bass without the typical nervous tuning-needle or LED.


  • Accurate tuning for guitars and basses.
  • Perfect behavior and ballistics.
  • Unique Output Dim feature: tune with sound but reduced in volume.
  • Can be used on multiple inputs to avoid plugging / unplugging of hardware tuners.
  • Easy, fast & affordable.
  • Included in the ENGL guitar amp plugins bundle.
