I purchased this on Mercari. I think it sounds good, but it wasn't quite right for me. But it's incredibly cool and just looking at it gets me pumped up. The noise gate is excellent, eliminating noise naturally and cleanly. It can be used widely, from classic brown sound to modern high gain. Setting the distortion to around 9 o'clock gives a pleasant crunch. - Brand: MXR - Model: 5150 overdrive - Controls: OUTPUT, BASS, MID, TREBLE, GAIN, BOOST - Gate function: GATE The box shows some signs of use, but the main unit is relatively clean. There are no electrical problems. Box, instruction manual, etc. are included.
