which cab should i buy for my Gallien & Krueger 700RB head? my specifications: it should be a flexible sounding cab since i´m playing in a stoner-/desertrock band (bass tuned down to C, much fuzz/distortion), i also love to play my active & passive basses clean and sometimes i play funky stuff with envelope filters and other effects. the cab is supposed to be used in our rehearsal room only and should have enough power for small gigs. i have no idea if i should go for 4x10", 2x12", 1x15" or whatever combination? with or without horn (G&K bi-amping)? 4 or 8 ohms? (i might want an option to add sometime later another cab) at the moment i tend to 2x12" ... does it make sense? thx for inspiration.
