Orange TT15JR Signature #4 Jim Root Terror 15-Watt Guitar Amp Head + matching PPC212JR 2x12” Closed-Back Cabinet

Kept and played at home mostly. Minor wear & tear from taking it to a jam sesh or two. No major damage, but could use a light cleaning of the grille cloth. Only selling because times are hard. Local pickup will be near Downtown Atlanta / Summerhill from a friend’s shop.

System Notes

The head is designed to sit directly on top of the matching cabinet, forming a compact half-stack. The power scaling switch reduces output stage voltage while retaining the same preamp and power tube complement. The valve-driven effects loop is wired in series after the preamp stage. Minimum recommended speaker load is 8 Ω. Speaker cable (unshielded) must always be used for cabinet connections.
