Thank you for viewing. I have been using this as my main amp for a long time, but I am selling it due to a change in equipment. It has been checked and there are no problems or crackling. This is a well-known, excellent amplifier. This is a high-performance bass amplifier with a clean section that forms the basis of tone, as well as distortion, overtones, and a micro tube engine that creates natural compression. Although not specifically for it, I will include the hard case and power cable that I was using. This is a used item with some scratches, so please understand that it is non-refundable and non-returnable.
