It's the second run AD5. In mint condition, even comes with it's original box. Only had light bedroom use. I put new valves in it about three hours playing ago. It has the Celestion G10N-40 speaker. Really is a great little combo.. smooth, warm vintage amp sounds. Takes effects/pedals really well also. Ideal for home use or recording. Loud for a 5w. I used it at home and rarely (if ever) had it past mid way.
