Poly Blue Octave MXR®

We offer a wide variety of products, and the following precautions apply to some of them. Please note that they are listed for all products. 【Voltage Compatibility】Designed for Japanese voltage (90-110V). Using with a different voltage may cause malfunction. 【Plug Type】Japanese plugs (A or B type). Use a conversion adapter if needed. 【Transformers & Adapters】Transformers adjust voltage; adapters only change plug shape. Using an adapter without a transformer may damage the product. 【Liability】We are not responsible for damages caused by improper use, such as using the product without a transformer. Modern and classic pitch shifting in one pedal. Four independent octave divisions, each with its own level control. Switch between polyphonic and monophonic pitch shifting. Add a thick, understated fuzz inspired by the MXR Blue Box Pedal. Control various parameters with an expression pedal or tap switch.
