I ordered this buffer based on it's price and footprint. it's intended to keep the sound of the guitar rich, smooth and natural and it does exactly that.
It's a really small box without any feautures other than the in- and output and the adapter input.
It's Just the way I like it. small, sturdy, industrial looking, no lights, no batteries good price and a great sound.
I velcro'd it to my pedal board but I could have used super glue as well. It's a keeper.
