HI I just saw a pretty clean looking Ampeg SVT AV head and 6-10 AV cabinet for sale at $1,400. Seller says he is th eorginila owner and only has 45 hours on the head. Is this a good combination and deal or something to avoid? I know about the weight - mainly for use in my studio. Head says Made in USA St Louis Music era. Any comments, as always, are appreciated!
