yeah.. simple question.. but i'm a n00b. i might buy a used svt 8x10 ($500!) and i was thinking of either buying a new b2-r or a 700rb2 head (unless something good and used comes along). someone told me that you can estimate about a 3:1 ratio for bass/guitar.. and i doubt i'll ever be playing with anyone with more then a half stack.. but is 350/400w really enough to power an 8x10???' thanks.
