I have not had any 15 cabs since I have started playing in the 70's and have been thinking about trying a single 15 cab as a stand alone or to use in conjunction with either a Tri112 Accugroove cab or a Tri210 Accugroove cab.I would prefer one of the UL cabs like a Epifani or a Bergantino.If anyone can give me any input on either of these cabs or any other maybe it may make my job of selecting one a little easier!
