Cheap but High Quality
Very basic sounding but delivers a great tone. Can't go wrong for the price. My friend recommended Donner to me and they're great for live performances. It really helps get a great tone with a single coil and breaks up the sound nicely, as well as giving clarity to each string.
Decent pedal, well worth the money.
This pedal is definitely good for bringing up the volume of your single-coiled guitars with high-compression, or for evening out the volume of chords with humbuckers at low compression. But trying to use compression above 10 or 11 o' clock with humbuckers or high-output pickups in general results in a breaking up of the signal that just doesn't sound good to my ears. But it IS well worth the money.
