Providing the warm, rich tone that Aguilar gear is famous for, the Chorusaurus uses analog bucket-brigade technology for lush, organic chorusing. The Chorusaurus gives bassists unparalleled control of their tone with an intuitive, four-knob layout. RATIO controls the ratio of dry and wet signals. The SPEED, INTENSITY, and WIDTH controls provide maximum tonal sculpting. Now you can dial in subtle swirling textures, extreme chorusing or anything in between! The Chorusaurus' output can be used for mono or stereo output. For stereo operation to two amplifiers, use a 1/4" Y cable with one 1/4" TRS to two 1/4" TS jacks. *Pedal powered by universal 9-volt power supply only. Not included.
