Mighty Plug Pro is the next evolutionary step in headphone amplifiers for guitar and bass players in a pocket-size and pocket-friendly format. Upgraded and updated from the original Mighty Plug, this new jack-mounted amp with effects also includes a full USB-audio interface (OTG) for recording and live-streaming over the internet (full headset connection via 3.5mm TRRS jack). Simply plug the Mighty Plug Pro into your guitar or bass and connect headphones and you can play fully amplified guitar sounds along to your favourite tracks in complete silence. Inside this tiny device is a huge arsenal of amp models for guitar or bass, effects and acoustic models, now extended with new models and IRs and flexible block routing. 7 presets are accessible by pressing the LED backlit button. Bluetooth connectivity lets you pair with a smart phone or tablet (search for "Mighty Plug Pro") for playback of audio to jam to or for in-depth editing of the Mighty Plug Pro amp and effect settings using the Mighty Amp app (downloadable from App Store or Google Play) or Mighty Editor software for PC (free to download from www.nuxefx.com). No need to keep replacing batteries, as the Mighty Plug Pro is rechargeable via the USB, which also serves as a computer interface for firmware updates and as a recording/playback interface. The Mighty Plug contains all you need for hours of practice, recording and sound exploration.
