Sorry if this is obvious to everyone but me, but I have sort of a beginners rig and have a question. I have a GK Backline 250head (only 125 watts but sounds much louder) running into a Carvin PS15 cab (1 15" speaker 400 watts @ 8 ohms). I like my tone, but notes played on the E string are significantly louder than the other strings regardless of the settings that I mess with on the head (turning up the hi-mid, for example). Is this pretty much because it is only a 15" speaker that is supplying all of the output? If I need to get a new cab and amp, what do you recommend I get for a good all around SINGLE cab that I can use to play small to medium size gigs. Is a 1x 15 OK, or would a 4x 10 or 2 x 12 be a better all purpose cab? I play alt/rock and have an active p/u bass. Thanks for any help.
