ok, so i just upgraded from my 3 pro, to a 400+. i was going to keep the 3 pro just as a back up/home practice amp, but i realized if i did this, i would have to get another cab for my house. so im thinking about selling the head to a friend, and buying a combo amp. just not sure what kind i should get. i usually dont pay combos any mind because ive only owned one over the years and it was a hartke p.o.s. so i guess what im asking is if i sell my 3 pro, what kind of combo should i look at? atleast 2-300 watts 15 or 2x10 or both easily portable something i can use as a back up in a live gig setting and have no problems finding power. like to saty in the mesag/ampeg family, but will take other suggestions offcourse, looking for something on wheels. i'd like it to be tube, but i will take a tube pre amp. please list me some suggestions.... thanks.
