Many were impressed by the tone that the ID:Core 40 can pour out of its stereo speakers, especially when the gain is cranked. And reviews constantly mention its incredibly versatility, thanks to the ISF knob. Some experienced players even commented that they found the tone to be very close to more expensive tube amps, and users have put it to good use in their bedrooms, living rooms, and offices.

There are some who complain about the lack of volume that this amp has for its power rating of 40W. Others find the controls and software companion to be a bit challenging, but this can easily be remedied by a cursory search on existing presets and user settings online.

    I have the Blackstar ID. Core 20 and it is as tube sounding as anything I’ve heard on the clean channel. I like it better than the new Boss Katana.
