USA PEOPLE:

Thanks to Trump, you might have to pay taxes and duties, while some people don’t; please consider this before buying. If the pedal is shipped and those taxes aren’t paid, t͟h͟e͟r͟e͟ ͟w͟i͟l͟l͟ ͟b͟e͟ ͟n͟o͟ ͟r͟e͟f͟u͟n͟d͟: I would have to pay them myself and could even face a fine, which gets very expensive. The same applies if you want to return a product you don’t like (obviously faulty pedals are excluded); in that case, the fee is €30. I’m sorry about this and hope things will change soon.

(ALL) pedals need a proper power supply,all of my pedals works with classic 9v.
Cheap, unshielded power supply will gets you background noise or pedals to not work at full potential, it's not something that depends on me, and it applies to all pedal, especially analog one, so please use a proper power supply.
