Blackstar certainly knows a bit about guitar amplification and then some, so when the brand releases an audio interface that it says is “designed by guitarists for guitarists”, it’s time to take notice.
The new Polar 2 is a solidly compact, bus-powered USB guitar audio interface with two identical inputs, each one equipped with a combo socket for a standard guitar cable or XLR mic cable. For monitoring, you have a standard pair of outputs to connect to your speaker system, plus a front-panel headphones jack with its own volume knob.
