Excerpt from the manufacturer's website below Features ・Compressor function "ATTACK" and "SUSTAIN" controls are designed with a gentle curve for easy adjustment to avoid sudden changes. ・Equipped with a newly designed dry mix circuit. The dry sound and effect sound mixing function allows for a wide range of sound creation. ・Equipped with HTS (Holistic Tonal Solution) circuit. Unlike conventional buffer circuits, the HTS circuit extracts the sound characteristics of guitars and basses to the maximum extent while performing impedance conversion, achieving both "high sound quality" and "low noise." This HTS circuit prevents the sound quality of guitars and basses from deteriorating even when the effect is off. ・The output signal is output in the same phase as the input signal, so there is no need to worry about phase inversion.
