This is a loop pedal with bypass of the English brand SuperKing.
For manufacturing, given the scale side, I think it directly at them but there is nothing to indicate the source.
It is formatted in Nano Electro-Harmonix Metal with LED turning on the loop and is true-bypass. It is powered by 9V battery. No possibility to supply standard Boss type.
I use it for about a week to cut my distortion + noise gate + eq at once and go in clean. I bought it to replace my Boss PSM-5 plugs for power supply and send / return was misplaced for my taste and the size larger.
What I like most is its mini size that fits in a pedalboard, the send / return a position contrary to the loop of my Boss noise gate NS-2 or the Boss PSM-5, true-bypass and the solid side. Damage to food by battery ...
I purchased 27 € with shipping on ebay (SuperKing has a shop on ebay and also sells on her website) so when have seen how it's done and the sale price of some brands, value for money is really not bad considering the quality and effectiveness of the product.
So what choice I would do without hesitation, in fact I intend to buy me one for my loop pedals.
