I've been using the same Peavey Mark VII with a Peavey 18" cab forever. I'm thinking that I'd like to add another cab so I can use the crossover and maybe not have to carry the 18 with me for rehearsals and smaller gigs. I'm thinking that a 1*10" should do it, a 2*10" max. Cheap is better as I'm not really playing out much or making money. I'm also playing mid 80 Peavey T-40s so I'm not needing the highest end performance... Any suggestions?
