Just picked up this pedal recently and it's one of the best muff variants I've owned in awhile. There is a slight issue though... I got it together with a Sunface TI/UK and while the Sunface stays relatively noise free (unless I do some crazy things with it), the BMP-1 gets really noisy when it's on - to the point where it's quite unplayable with the "fuzz" knob cranked. Was hoping you people could shed some light on this issue! I power it with a PP2+. Pedalchain is as follows: Sunface --> Polytune --> TS808 --> Dumkudo --> SL Drive --> BMP-1 --> Timeline Cheers all!!!!!!!!!!!
