I have an itch for a JCM 800. Local sale for a used 2203x for $1200 excellent condition. I don't play out. I have been focused on the SC20 head until this 2203x popped up for sale. I would be running either through my SJ 4x12 with v30s. I also have an empty SJ 2555X head shell. Would a 2203x chassis fit a 2555x head shell box?
