“Elevating its feature set for professional recording and production situations”: Blackstar’s Polar 4 pitches for the pro player by supersizing the guitar-focused audio interface

Blackstar has unveiled the latest iteration of its audio interface for guitarists, the Polar 4, which expands on the recently announced Polar 2 with new MIDI connectivity and up to four instrument inputs.

The Polar 2 was only unveiled in early July, but caused a stir among players with its promises to address what Blackstar outlined as the three key weaknesses of the audio interface market for guitarists, namely: ease of use, setting guitar input levels and poor feel/response.
