It has a flat bass response at around 20 cm (around 8 inches). At 100 cm (around 39-inches) from the sound source it's down around 5 dB at 160 Hz and around 12 dB at 50 Hz. Beyond that it will be slightly more rolled-off.
If you were to use it for concert recording, you'd have to EQ the bass up quite a bit in post-production.
Its off-axis fall-off is reasonable within +/- 30 degrees and it has the rejection you'd expect of a supercardioid at 90 and 180 degrees.
My opinion is that it's not suitable for concert recording unless used in an array with other mics. When mounted properly on instruments it's an excellent sounding mic.
