Thank you for viewing. This is a handmade effector purchased from you on Mercari. I believe it captures the characteristics of the rumored VEMURAM Myriad Fuzz very well. Even without comparing it to the actual unit, it gives the impression that you can create various types of usable sounds. I have only used it a few times at home. The knobs have been replaced. The default knobs are also included. The bottom three knobs are a bit stiff, possibly due to the original specifications. This is an item for sale, the unit only. I am selling it because the type of sound I use has changed. <Specifications> Bypass: True Bypass Power: DC9v Center Negative (Battery not supported) Knobs: LEVEL, FUZZ (top row, left to right) FEEL, BIAS, TONE (bottom row, left to right) (The sound may not come out depending on the BIAS setting, but this is normal operation.)
