VOX Bulldog Distortion This is a vacuum tube distortion effects pedal. You can switch between Gain 1 and 2 separately from turning the effect on and off. I bought it on Mercari and it arrived yesterday. I tested it out, but it wasn't to my liking, so I'm selling it. The unit only. It produces a very tube-like sound, so I think it will appeal to those who like that. There are many introductions on Youtube, so please refer to those. I'm selling it for much less than the purchase price. Please check the condition in the images. Electric guitar, effects pedal
