FENDER RUMBLE 25 JP specifications. I purchased this about a year ago for practicing bass at home. There are no noticeable scratches or crackling. The metal parts have some slight dulling. I don't smoke, and I don't have any pets, so there are no odors. The sound quality is clear and perfect for practice, but it can get quite loud, so I'm putting it up for sale because I don't use it much at home. The box, instruction manual, and power cord are all included.
