Thank you very much for viewing. I am selling the Organic Sounds treble booster, "Poseidon." There is no crackling, and it is in excellent condition with almost no scratches. Just in case, there may be some minor scratches, so please check the images. I purchased it new and used it with care in a room free of pets and tobacco. I am selling it because I have fewer opportunities to use it and to organize my equipment. Returns are not accepted, so please understand and accept this.
