now, i have my ampeg head.. my ampeg 4x10 8-ohm cabinet.... I love the 4x10s.. and my 15 i use to have (peavey) sounded good when i had it all together. But there is always hype about 4x10s.. but there is NOWHERE here to try out the two. What do you think I should do? Get another 4x10, so i would have 2 seperate 4x10 cabs.. or add the 15?
