Price reduced until October 19th. Custom exterior model. Purchased new in June 2025. Used for a few studio rehearsals and live performances. As an amplifier, it was a head that produced a truly wonderful tone and power, as rumored, but it didn't match the sound the band was looking for, so I'm putting it up for sale, hoping someone else will find it more suitable. It hasn't been taken out much, and there are no noticeable stains or scratches. There are no problems with the operation or sound output. There is no crackling in the knobs. An unused power cable is included. It will be packed in the original box in the same way it was when purchased and shipped. I'm not particularly in a hurry to sell this item, so please refrain from price negotiations. I intend to gradually adjust the price if it doesn't sell, so I would like to sell it to someone who is satisfied with the price.
