BigRock is an authentic, accurately modeled emulation of the legendary Electro-Harmonix Small Stone, a phase shifting stomp box, of which its first revision was released in 1974.

However, being 2010, ArtsAcoustic has of course overcome most of the limitations of the original and equipped BigRock with the necessary features in an special advanced mode. For example, BigRock allows stereo input and processes the signal in stereo, while the original Small Stone was strictly mono. Essentially, you now have the ability to edit BigRock in most of the common phaser parameters such as the dry/wet mix, the center frequency, the LFO amount and the stereo phase offset of the LFO. You can also sync the LFO frequency to the host, always in phase to the sequencer's play position.

ArtsAcoustic also equipped the BigRock with a highpass/lowpass filter section, so you can balance out the signal, before it enters the phaser stage. The two resonance states on the original Small Stone are actually two different designs, it's not just more or less resonance by far. On BigRock ArtsAcoustic implemented a continuous parameter, so you can now morph between the original high color and low color mode, or adjust anything in between. Of course, as all parameters in the BigRock are automatable, this opens a tremendous amount of creative possibilities, all of which were not possible with the original Small Stone.
