I have owned a 370 since new in 1974. Love it; just too loud for what I have been doing lately.
My wife bought me a GC Acoustic B200 combo in 2009; I still love it. I have joined a band which has tons of JBL PA and I plan to use the DI as well as the amp itself..I digress..
So a mention was made at a band meeting about having to haul our stuff up a couple of flights of stairs at an upcoming gig. A B200 H with seperate cab weighs less [seperately] than my B200 Combo. Last Saturday, my wife drives us to the Fayetteville GC and suggested I order a seperate head and cab for weight reduction..I LOVE MY WIFE..... My fave G C sales guy, Steve searched system-wide and found me a new-in-the-box B200 head and 1x15 cab for $100 less than my B200 combo cost 3 years ago. All I have to do is wait until it is shipped to the store and I will have yet another GC Acoustic amp.
I believe that the B200 Head can also run 2 cabs without an ohmage issue; unlike the B200 combo. If needed, I can run the B200 H and 1x15 cab stacked on my Marshall 1550 cab, or oddly paired with my trusty old/ heavy Kustom 200 cab
[ 2x15]. Ultimately, I want to run my Rick 4001 in stereo; one P/U per Acoustic amp; don't know which will be bridge or neck amp yet. I'll keep y'all posted.
I am sure the the newer Acoustic heads will obsolete the lower wattage heads, but I don't need any more wattage or I would use my 370 head, which weighs 45 pounds; also a weight issue, as well as the Sunn Cab it ususally goes through.
