I have an Ampeg SVT 350h head now and a friend of mine has a 70's Ampeg V4b. i was thinking about trading him, but im not quite sold on weather or not it's a good idea. i've owned my 350h for 4 er 5 years now and it does the job pritty well, but it doesnt have the head room or sheer vloume i'd prefer for playing live with drums in a metal band. i love tube heads, and i've played many. but this V4b is in kinda rough shape, it's just standard wear and tear from use, but my 350 is in tip top shape. i know i could have it retubed and i know a pro who would do it for very cheap. so what it really comes down to is whitch head is better the 350H or the 70's V4B? any comments on eather amp would be great too bad or good. plzz help.
