Allmusic reviewer Phil Freeman states "While the group is capable of Ayler-esque blare, the two horn players (McPhee switches back and forth between saxophones and trumpet or cornet) can also bring things down quite a bit, murmuring introspective phrases with the rhythm section at rest. This happens during each of the two long pieces that make up Guts, and it helps give the listener's ears a momentary break, but also builds tension for when the full ensemble comes back".
